CMYK: adjustment layers composite on the document's own inks (14 oracles pass) (#4945)
* Modern Brightness/Contrast: Photoshop's brightness curve The modern brightness curve was a line rolled off by a v^P term. It sat up to 4 levels off Photoshop's in the highlights, and up to 2.3 levels off for lowered brightness. The curve is refit to the Photoshop ground truth we have: - the ±50 samples from 4759d12b; - the photoshop corpus's brightness +25 / contrast +30 files, inverted through the (exact) contrast curve. Raised, it is the line s*x (s = 1.375^(b/50)) up to a knee at 80/255, then a cubic Hermite to white with end slope s^-6.6. Lowered, it is the exact inverse of the curve raised by as much (the -50 samples confirm this to within a level). Every measured point is within about a level. For strong values the knee moves down so the curve stays monotone across -150..150. Brightness then contrast are evaluated through one 4096-entry table, built in 55 us. The GPU uses that same table through the Levels/Curves kernel instead of rebuilding the curves in WGSL, so GPU and CPU agree by construction. Photoshop oracles: rgb8/16/32 and gray8/16/32 brightness-contrast now pass (145 -> 151 of 258). The floor goes 133 -> 151. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK: Brightness/Contrast curves each ink, as Photoshop does Photoshop applies Brightness/Contrast in a CMYK document to each ink's stored value, 1 - ink, black included. Both the modern and the legacy curve do this; the cmyk8 brightness-contrast(-legacy) oracles match it within a level on every pixel of the files' own inks. Raising brightness takes ink away. We applied it to the screen colour instead. - cmyk_channel_adjustment gains Brightness/Contrast. apply_in builds the channel curve once (brightness_contrast_lut) and runs each separated ink through it (ink_through). - Destructive Image > Adjustments on a CMYK layer curves the stored inks directly, so it is exact; a selection mixes them. adjusted_channels now takes the per-pixel operation, and works out luma only for CMYK Threshold, which compares it. - The GPU leaves CMYK Brightness/Contrast to the CPU, like the other ink rules. cmyk8/16 brightness-contrast oracles, bad pixels: - modern: 72% -> 48-57%, max error 0.19 -> 0.09 - legacy: 71% -> 51-53% The rest is our separation of the RGB composite, not the rule. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK Threshold compares the inks' own luma, as Photoshop does Photoshop's CMYK Threshold splits on the Rec. 601 luma of the inks' plain complement, (1 - c)(1 - k) and so on, whatever the document's profile. On the files' own inks this puts every pixel of cmyk8 and cmyk16 threshold-128.psd on the right side of level 128. The profile's RGB luma missed 100. stored_channels works the luma out from the inks itself (ink_luma), so it no longer takes one; the engine's stored-channel path no longer converts each pixel to RGB at all. Through the separated RGB composite the cmyk threshold oracles drop from 1.6% to 0.2% bad pixels. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK legacy Brightness/Contrast pivots at 128 in ink Photoshop's legacy contrast pivots at level 128 of the ink, which is 127 of 255 of the stored value (1 - ink) that the curve runs on, not 128 as in RGB. On Photoshop's own 16-bit inks (cmyk16 brightness-contrast-legacy.psd) ours sat a constant 0.43 of a level above. That is exactly the one-level pivot shift times contrast +30's slope minus one; with the pivot moved, the inks match within 0.01. brightness_contrast_lut is now ink_brightness_contrast_lut, since its legacy curve is the CMYK one. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK: adjustment layers composite on the document's own inks The compositor works in display RGB. In a CMYK document, an adjustment layer that Photoshop evaluates on the inks could only act on our separation of the RGB composite, and that separation's black differs from the file's. So even exact ink rules missed: CMYK Invert was 10% off, Levels and Curves 50-65%. The ink-native compositor (compose::native, until now only for flattening plain raster stacks) now takes adjustment layers too: - Invert, Posterize, Threshold and Brightness/Contrast (modern and legacy), and Levels and Curves on CMYK channels, prepared once (InkStack, InkOp) and applied to the straight inks. - Opacity and an unfeathered layer mask mix the inks linearly, as in Photoshop; raster layers' masks scale their coverage the same way. - A CMYK stack of plain raster layers and such adjustments renders this way for display, export and reduced views (render_cmyk, tiles in parallel); flattening and merging keep the adjusted inks exactly. - Stacks of raster layers alone keep the RGB compositor, which the GPU matches. The GPU already leaves these adjustments to the CPU. Photoshop oracles: cmyk8 and cmyk16 invert, posterize-4, threshold-128, levels, curves, brightness-contrast and brightness-contrast-legacy all pass (14 files), 151 -> 165 of 258; floor 151 -> 165. psd-tools and io corpora unchanged. 24 MP CMYK8 with one adjustment renders in 286 ms on the inks, against 442 ms through the RGB compositor. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK ink compositing inlines open groups The ink compositor gave up on any group. Now a group at full opacity without a mask is inlined: - a pass-through group's children composite straight onto the backdrop, so an adjustment inside it reaches the layers below; - an isolated (Normal) group of raster layers alone composites as its children would, since Normal is associative. An isolated group with an adjustment, which only sees the group's content, keeps the RGB compositor. So do a translucent group and an artboard. Nesting is bounded. psd-tools' CMYK adjustment files keep their swatches in pass-through groups. With #4948's fair comparison, curves_cmyk drops from 37% to 0.3% bad pixels and levels_cmyk from 14% to 0.2%. The photoshop corpus is unchanged at 165. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 32-bit: legacy Brightness/Contrast, Channel Mixer, Photo Filter and B&W tint unclipped In 32-bit documents Photoshop keeps these adjustments' results above 1 and below 0. On the photoshop corpus's rgb32/gray32 files: - Legacy Brightness/Contrast pivots its contrast at 127 of 255 (8/16-bit: 128) and is exact on every pixel. - Channel Mixer cuts each source percentage to 1/1024 toward zero, counts 255/512 of the constant and is exact on pure red, green, blue, black and white. - Photo Filter works on the linear samples, negative results included. - The Black & White tint is the Color blend mode without the clip at 1, as the blend mode is there; white tints to (1.05, 1.00, 0.87). We clipped all four to 0..1. The GPU kernels follow suit under F_HDR (the legacy pivot and the mixer's steps come from the planner), and the HDR parity test covers them. Photoshop oracles: rgb32 and gray32 brightness-contrast-legacy, rgb32 channel-mixer and black-white-tint pass (145 -> 149 of 258); floor 145 -> 149. rgb32 photo-filter improves (0.19 -> 0.035 max); the rest is its colour (#3790). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Modern brightness: knee at output 126, fit out to -95 and +150 psd-tools' brightnesscontrast_rgb.psd masks four Brightness/Contrast layers to their own columns. Read through the exact contrast curve, it gives Photoshop's brightness at -95, -31, +23 and +150, well past the +/-50 samples the first fit had. The +/-50 curve extrapolated badly there: 22 levels off at -95 and 25 at +150. Every setting puts the knee at about the same output level, not input. The roll-off's end slope falls as 1/(1 + 0.084 b). With the knee at 126/255 and that end slope, the cubic Hermite fits -95, -50, -31, +23, +25 and +50 within 1.4 levels. Past about +110 no such cubic stays below white, so there the roll-off is 1 - (1 - y0)(1 - u)^alpha, with the slope continuous at the knee. That gives +150 within 6 levels, where every curve family tried bottoms out. Lowered curves are still the inverse of raised ones. The photoshop corpus's six brightness-contrast oracles still pass. psd-tools brightnesscontrast_rgb goes from 0.13 to 0.020 max error and _grayscale from 0.098 to 0.016. The new measurements are pinned in modern_brightness_matches_photoshop. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Levels: whole levels at every step and Photoshop's shadow toe In 8 bits Photoshop rounds each of the three Levels steps to a whole level (half up): the input-range stretch (already modelled), the midtone gamma and the output range. A narrow output range therefore merges neighbouring gamma levels: psd-tools levels_rgb maps R 43..48 to 58 through a 0.47 channel gamma and the master's 48..255, where the unrounded curve gave 56..59 (3 levels off in blue). The gamma above 1 starts along a toe a*u - b*u^q of slope a = 2^gamma that joins the power curve with the same value and slope (q = 2.2, fitted). With the rounding, that is exact on 1116 of the 1118 levels of gamma 1.16, 1.22, 1.3, 1.78 and 2.0 oracles; the soft-min it replaces missed 52. Gamma below 1 stays the plain power curve (0.67 and 0.7: every level exact). Oracles: psd-tools levels_rgb 0.0118 -> 0.0039 (PASS); photoshop rgb8/stack-levels-curves-hue-posterize 0.2000 -> 0.0000 (PASS); rgb8 and gray8 levels.psd 0.0039 -> 0.0000; rgb16/gray16 0.0039 -> 0.0020. Floors: photoshop 145 -> 146, psd-tools 236 -> 238 (main is at 237). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Masks: feathers blur with exactly the feather's variance A mask feather is a Gaussian with sigma = feather, which we approximate with three box passes per axis. Whole-pixel boxes rounded the variance: a 6 px feather blurred like 6.48 px and a 3 px one like 3.46 px, so feathered edges were too soft by up to 4 levels against Photoshop (psd-tools mask-parameters-no-real-channel.psd: a 6 px vector and 3 px pixel feather). Each pass is now an "extended box" (Gwosdek et al. 2011): weight 1 on the whole radius and a fractional weight on the two samples beyond it, so three passes have variance sigma^2 exactly. It stays O(n), reusing the window's leaving sample for the low end weight (50 MP at a 1000 px feather: 180 ms parallel, was 172). psd-tools: mask-parameters-no-real-channel 0.0168 -> 0.0060 (PASS), layer_mask_data.psd 26.9 % -> 3.9 % of pixels off (psb 25.9 % -> 1.8 %). Corpus test 239 -> 240; floor 236 -> 240. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Lab: adjustment layers composite on the stored L, a and b The compositor reads a Lab document's layers through display RGB, which clips colours outside its gamut, so the adjustments Photoshop evaluates on L, a and b (Invert, Posterize, Threshold, Brightness/Contrast, Levels and Curves with Lab records) only saw the clipped colours: the photoshop corpus's Lab oracles were up to 11 levels off on saturated colours. compose::native_lab works a Lab stack of plain layers out on the stored values instead, like the CMYK ink path: Normal mixes L, a and b linearly, an opaque layer keeps them exactly, a layer mask scales the mix, and adjustment layers run adjust::lab_stored_op on each pixel. Stacks with such adjustments render for display this way; flattening a plain Lab stack keeps its stored values (exports no longer clip). Anything else (other blend modes, effects, other adjustments) keeps the RGB compositor. Photoshop oracles 145 -> 152: lab16 invert, posterize-4, levels, curves and brightness-contrast-legacy; lab8 invert and posterize-4. lab8 levels and legacy B/C come within a level (their 8-bit rules are #5143 and #5132). psd-tools and io unchanged; every round trip unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Threshold: split on Photoshop's luminosity of whole samples Photoshop's Threshold splits on the luminosity 0.30 R + 0.59 G + 0.11 B (the blend modes' lum, as Gradient Map uses), not the Rec. 601 grey, taken over the document's whole sample values: - 8 bits: 30 R + 59 G + 11 B > 100 level - 50, i.e. the luminosity rounded to a level with halves down reaches the level; - 16 bits: 30 R + 59 G + 11 B >= 100 x the level in 16 bits (round(level x 32768 / 255): mid grey 16448 is level 128); - 32 bits: the luminosity reaches the level. Exact on every pixel of psd-tools threshold_rgb (36432 px; Rec. 601 split 28 the other way), threshold_16bits_rgb (100) and threshold_16bits_ grayscale, and the photoshop corpus's rgb16 threshold-128. The sums are exact in f32, on the CPU and in the GPU kernel, so ties (grey exactly on the level) split the same way on both. psd-tools: threshold_rgb and threshold_16bits_rgb pass; corpus test 239 -> 241, floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Posterize: 16-bit documents bin the 16-bit sample, as Photoshop does At 16 bits Photoshop doesn't round to 8-bit levels before binning. It bins the 16-bit sample, floor(v16 * n / 32768), and lands on 8-bit levels through a 16-bit step: floor(b * 32768 / (n - 1)), converted with floor((o * 255 + 16384) / 32768). So the middle of 3 levels is 128 where 8 bits give 127, while 42.5 and 25.5 stay 42 and 25. Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges. The same rule applies to CMYK and Lab channels at 16 bits: on the stored inks (#4945's native path) psd-tools posterize_16bits_cmyk goes from 4.26 % to 0.01 % of pixels off. 8-bit Posterize is unchanged. The GPU kernel runs the same rule; 16-bit layers reach it as half floats, so a sample within their precision of a bin edge can land in the neighbouring bin there (the CPU, which exports, is exact). psd-tools 239 -> 241; floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK: Posterize works on the stored values (1 - ink) Photoshop posterizes a CMYK channel's stored value, 1 - ink, not the ink: with levels whose steps are uneven (3, 7, 13, 21) the two differ, e.g. 3 levels take an ink of 85 to 128, where posterizing the ink drops it to none. psd-tools posterize_cmyk.psd goes from 13.8 % of pixels off to exact; psd-tools 241 -> 242, floor 242. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Groups: a pass-through clipping base with an adjustment renders isolated A pass-through group composites its children straight into the backdrop, so an adjustment layer inside reaches the layers beneath. When the group is the base of a clipping group and holds an adjustment layer, Photoshop renders it isolated instead: in psd-tools passthrough_clipping_mask_adjustment an Exposure in such a group leaves the layers beneath alone (we darkened them: half the image 170 levels off). The same group with a Linear Dodge child and no adjustment keeps reaching the backdrop (passthrough_clipping_mask_blendmode), and so do clipping-mask3/4/5, so the rule is the adjustment, not the clipping alone (isolating every pass-through clipping base broke those two). CPU compositor and GPU plan alike. psd-tools 239 -> 240; floor 240.

CMYK: Brightness/Contrast curves each ink, as Photoshop does (#4930)
* Modern Brightness/Contrast: Photoshop's brightness curve The modern brightness curve was a line rolled off by a v^P term. It sat up to 4 levels off Photoshop's in the highlights, and up to 2.3 levels off for lowered brightness. The curve is refit to the Photoshop ground truth we have: - the ±50 samples from 4759d12b; - the photoshop corpus's brightness +25 / contrast +30 files, inverted through the (exact) contrast curve. Raised, it is the line s*x (s = 1.375^(b/50)) up to a knee at 80/255, then a cubic Hermite to white with end slope s^-6.6. Lowered, it is the exact inverse of the curve raised by as much (the -50 samples confirm this to within a level). Every measured point is within about a level. For strong values the knee moves down so the curve stays monotone across -150..150. Brightness then contrast are evaluated through one 4096-entry table, built in 55 us. The GPU uses that same table through the Levels/Curves kernel instead of rebuilding the curves in WGSL, so GPU and CPU agree by construction. Photoshop oracles: rgb8/16/32 and gray8/16/32 brightness-contrast now pass (145 -> 151 of 258). The floor goes 133 -> 151. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK: Brightness/Contrast curves each ink, as Photoshop does Photoshop applies Brightness/Contrast in a CMYK document to each ink's stored value, 1 - ink, black included. Both the modern and the legacy curve do this; the cmyk8 brightness-contrast(-legacy) oracles match it within a level on every pixel of the files' own inks. Raising brightness takes ink away. We applied it to the screen colour instead. - cmyk_channel_adjustment gains Brightness/Contrast. apply_in builds the channel curve once (brightness_contrast_lut) and runs each separated ink through it (ink_through). - Destructive Image > Adjustments on a CMYK layer curves the stored inks directly, so it is exact; a selection mixes them. adjusted_channels now takes the per-pixel operation, and works out luma only for CMYK Threshold, which compares it. - The GPU leaves CMYK Brightness/Contrast to the CPU, like the other ink rules. cmyk8/16 brightness-contrast oracles, bad pixels: - modern: 72% -> 48-57%, max error 0.19 -> 0.09 - legacy: 71% -> 51-53% The rest is our separation of the RGB composite, not the rule. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK Threshold compares the inks' own luma, as Photoshop does Photoshop's CMYK Threshold splits on the Rec. 601 luma of the inks' plain complement, (1 - c)(1 - k) and so on, whatever the document's profile. On the files' own inks this puts every pixel of cmyk8 and cmyk16 threshold-128.psd on the right side of level 128. The profile's RGB luma missed 100. stored_channels works the luma out from the inks itself (ink_luma), so it no longer takes one; the engine's stored-channel path no longer converts each pixel to RGB at all. Through the separated RGB composite the cmyk threshold oracles drop from 1.6% to 0.2% bad pixels. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * CMYK legacy Brightness/Contrast pivots at 128 in ink Photoshop's legacy contrast pivots at level 128 of the ink, which is 127 of 255 of the stored value (1 - ink) that the curve runs on, not 128 as in RGB. On Photoshop's own 16-bit inks (cmyk16 brightness-contrast-legacy.psd) ours sat a constant 0.43 of a level above. That is exactly the one-level pivot shift times contrast +30's slope minus one; with the pivot moved, the inks match within 0.01. brightness_contrast_lut is now ink_brightness_contrast_lut, since its legacy curve is the CMYK one. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 32-bit: legacy Brightness/Contrast, Channel Mixer, Photo Filter and B&W tint unclipped In 32-bit documents Photoshop keeps these adjustments' results above 1 and below 0. On the photoshop corpus's rgb32/gray32 files: - Legacy Brightness/Contrast pivots its contrast at 127 of 255 (8/16-bit: 128) and is exact on every pixel. - Channel Mixer cuts each source percentage to 1/1024 toward zero, counts 255/512 of the constant and is exact on pure red, green, blue, black and white. - Photo Filter works on the linear samples, negative results included. - The Black & White tint is the Color blend mode without the clip at 1, as the blend mode is there; white tints to (1.05, 1.00, 0.87). We clipped all four to 0..1. The GPU kernels follow suit under F_HDR (the legacy pivot and the mixer's steps come from the planner), and the HDR parity test covers them. Photoshop oracles: rgb32 and gray32 brightness-contrast-legacy, rgb32 channel-mixer and black-white-tint pass (145 -> 149 of 258); floor 145 -> 149. rgb32 photo-filter improves (0.19 -> 0.035 max); the rest is its colour (#3790).

Corpus test 239 -> 240; floor 236 -> 240.

Exact on every pixel of psd-tools threshold_rgb (36432 px; Rec. 601 split 28 the other way), threshold_16bits_rgb (100) and threshold_16bits_ grayscale, and the photoshop corpus's rgb16 threshold-128.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Posterize: 16-bit documents bin the 16-bit sample, as Photoshop does At 16 bits Photoshop doesn't round to 8-bit levels before binning. It bins the 16-bit sample, floor(v16 * n / 32768), and lands on 8-bit levels through a 16-bit step: floor(b * 32768 / (n - 1)), converted with floor((o * 255 + 16384) / 32768). So the middle of 3 levels is 128 where 8 bits give 127, while 42.5 and 25.5 stay 42 and 25. Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges. The same rule applies to CMYK and Lab channels at 16 bits: on the stored inks (#4945's native path) psd-tools posterize_16bits_cmyk goes from 4.26 % to 0.01 % of pixels off. 8-bit Posterize is unchanged. The GPU kernel runs the same rule; 16-bit layers reach it as half floats, so a sample within their precision of a bin edge can land in the neighbouring bin there (the CPU, which exports, is exact). psd-tools 239 -> 241; floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Groups: a pass-through clipping base with an adjustment renders isolated A pass-through group composites its children straight into the backdrop, so an adjustment layer inside reaches the layers beneath. When the group is the base of a clipping group and holds an adjustment layer, Photoshop renders it isolated instead: in psd-tools passthrough_clipping_mask_adjustment an Exposure in such a group leaves the layers beneath alone (we darkened them: half the image 170 levels off). The same group with a Linear Dodge child and no adjustment keeps reaching the backdrop (passthrough_clipping_mask_blendmode), and so do clipping-mask3/4/5, so the rule is the adjustment, not the clipping alone (isolating every pass-through clipping base broke those two). CPU compositor and GPU plan alike. psd-tools 239 -> 240; floor 240.

Modern Brightness/Contrast: Photoshop's brightness curve (six oracles pass) (#4722)
* Modern Brightness/Contrast: Photoshop's brightness curve The modern brightness curve was a line rolled off by a v^P term. It sat up to 4 levels off Photoshop's in the highlights, and up to 2.3 levels off for lowered brightness. The curve is refit to the Photoshop ground truth we have: - the ±50 samples from 4759d12b; - the photoshop corpus's brightness +25 / contrast +30 files, inverted through the (exact) contrast curve. Raised, it is the line s*x (s = 1.375^(b/50)) up to a knee at 80/255, then a cubic Hermite to white with end slope s^-6.6. Lowered, it is the exact inverse of the curve raised by as much (the -50 samples confirm this to within a level). Every measured point is within about a level. For strong values the knee moves down so the curve stays monotone across -150..150. Brightness then contrast are evaluated through one 4096-entry table, built in 55 us. The GPU uses that same table through the Levels/Curves kernel instead of rebuilding the curves in WGSL, so GPU and CPU agree by construction. Photoshop oracles: rgb8/16/32 and gray8/16/32 brightness-contrast now pass (145 -> 151 of 258). The floor goes 133 -> 151. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * 32-bit: legacy Brightness/Contrast, Channel Mixer, Photo Filter and B&W tint unclipped In 32-bit documents Photoshop keeps these adjustments' results above 1 and below 0. On the photoshop corpus's rgb32/gray32 files: - Legacy Brightness/Contrast pivots its contrast at 127 of 255 (8/16-bit: 128) and is exact on every pixel. - Channel Mixer cuts each source percentage to 1/1024 toward zero, counts 255/512 of the constant and is exact on pure red, green, blue, black and white. - Photo Filter works on the linear samples, negative results included. - The Black & White tint is the Color blend mode without the clip at 1, as the blend mode is there; white tints to (1.05, 1.00, 0.87). We clipped all four to 0..1. The GPU kernels follow suit under F_HDR (the legacy pivot and the mixer's steps come from the planner), and the HDR parity test covers them. Photoshop oracles: rgb32 and gray32 brightness-contrast-legacy, rgb32 channel-mixer and black-white-tint pass (145 -> 149 of 258); floor 145 -> 149. rgb32 photo-filter improves (0.19 -> 0.035 max); the rest is its colour (#3790). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Modern brightness: knee at output 126, fit out to -95 and +150 psd-tools' brightnesscontrast_rgb.psd masks four Brightness/Contrast layers to their own columns. Read through the exact contrast curve, it gives Photoshop's brightness at -95, -31, +23 and +150, well past the +/-50 samples the first fit had. The +/-50 curve extrapolated badly there: 22 levels off at -95 and 25 at +150. Every setting puts the knee at about the same output level, not input. The roll-off's end slope falls as 1/(1 + 0.084 b). With the knee at 126/255 and that end slope, the cubic Hermite fits -95, -50, -31, +23, +25 and +50 within 1.4 levels. Past about +110 no such cubic stays below white, so there the roll-off is 1 - (1 - y0)(1 - u)^alpha, with the slope continuous at the knee. That gives +150 within 6 levels, where every curve family tried bottoms out. Lowered curves are still the inverse of raised ones. The photoshop corpus's six brightness-contrast oracles still pass. psd-tools brightnesscontrast_rgb goes from 0.13 to 0.020 max error and _grayscale from 0.098 to 0.016. The new measurements are pinned in modern_brightness_matches_photoshop. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Levels: whole levels at every step and Photoshop's shadow toe In 8 bits Photoshop rounds each of the three Levels steps to a whole level (half up): the input-range stretch (already modelled), the midtone gamma and the output range. A narrow output range therefore merges neighbouring gamma levels: psd-tools levels_rgb maps R 43..48 to 58 through a 0.47 channel gamma and the master's 48..255, where the unrounded curve gave 56..59 (3 levels off in blue). The gamma above 1 starts along a toe a*u - b*u^q of slope a = 2^gamma that joins the power curve with the same value and slope (q = 2.2, fitted). With the rounding, that is exact on 1116 of the 1118 levels of gamma 1.16, 1.22, 1.3, 1.78 and 2.0 oracles; the soft-min it replaces missed 52. Gamma below 1 stays the plain power curve (0.67 and 0.7: every level exact). Oracles: psd-tools levels_rgb 0.0118 -> 0.0039 (PASS); photoshop rgb8/stack-levels-curves-hue-posterize 0.2000 -> 0.0000 (PASS); rgb8 and gray8 levels.psd 0.0039 -> 0.0000; rgb16/gray16 0.0039 -> 0.0020. Floors: photoshop 145 -> 146, psd-tools 236 -> 238 (main is at 237). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Masks: feathers blur with exactly the feather's variance A mask feather is a Gaussian with sigma = feather, which we approximate with three box passes per axis. Whole-pixel boxes rounded the variance: a 6 px feather blurred like 6.48 px and a 3 px one like 3.46 px, so feathered edges were too soft by up to 4 levels against Photoshop (psd-tools mask-parameters-no-real-channel.psd: a 6 px vector and 3 px pixel feather). Each pass is now an "extended box" (Gwosdek et al. 2011): weight 1 on the whole radius and a fractional weight on the two samples beyond it, so three passes have variance sigma^2 exactly. It stays O(n), reusing the window's leaving sample for the low end weight (50 MP at a 1000 px feather: 180 ms parallel, was 172). psd-tools: mask-parameters-no-real-channel 0.0168 -> 0.0060 (PASS), layer_mask_data.psd 26.9 % -> 3.9 % of pixels off (psb 25.9 % -> 1.8 %). Corpus test 239 -> 240; floor 236 -> 240. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Lab: adjustment layers composite on the stored L, a and b The compositor reads a Lab document's layers through display RGB, which clips colours outside its gamut, so the adjustments Photoshop evaluates on L, a and b (Invert, Posterize, Threshold, Brightness/Contrast, Levels and Curves with Lab records) only saw the clipped colours: the photoshop corpus's Lab oracles were up to 11 levels off on saturated colours. compose::native_lab works a Lab stack of plain layers out on the stored values instead, like the CMYK ink path: Normal mixes L, a and b linearly, an opaque layer keeps them exactly, a layer mask scales the mix, and adjustment layers run adjust::lab_stored_op on each pixel. Stacks with such adjustments render for display this way; flattening a plain Lab stack keeps its stored values (exports no longer clip). Anything else (other blend modes, effects, other adjustments) keeps the RGB compositor. Photoshop oracles 145 -> 152: lab16 invert, posterize-4, levels, curves and brightness-contrast-legacy; lab8 invert and posterize-4. lab8 levels and legacy B/C come within a level (their 8-bit rules are #5143 and #5132). psd-tools and io unchanged; every round trip unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Threshold: split on Photoshop's luminosity of whole samples Photoshop's Threshold splits on the luminosity 0.30 R + 0.59 G + 0.11 B (the blend modes' lum, as Gradient Map uses), not the Rec. 601 grey, taken over the document's whole sample values: - 8 bits: 30 R + 59 G + 11 B > 100 level - 50, i.e. the luminosity rounded to a level with halves down reaches the level; - 16 bits: 30 R + 59 G + 11 B >= 100 x the level in 16 bits (round(level x 32768 / 255): mid grey 16448 is level 128); - 32 bits: the luminosity reaches the level. Exact on every pixel of psd-tools threshold_rgb (36432 px; Rec. 601 split 28 the other way), threshold_16bits_rgb (100) and threshold_16bits_ grayscale, and the photoshop corpus's rgb16 threshold-128. The sums are exact in f32, on the CPU and in the GPU kernel, so ties (grey exactly on the level) split the same way on both. psd-tools: threshold_rgb and threshold_16bits_rgb pass; corpus test 239 -> 241, floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Posterize: 16-bit documents bin the 16-bit sample, as Photoshop does At 16 bits Photoshop doesn't round to 8-bit levels before binning. It bins the 16-bit sample, floor(v16 * n / 32768), and lands on 8-bit levels through a 16-bit step: floor(b * 32768 / (n - 1)), converted with floor((o * 255 + 16384) / 32768). So the middle of 3 levels is 128 where 8 bits give 127, while 42.5 and 25.5 stay 42 and 25. Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges. The same rule applies to CMYK and Lab channels at 16 bits: on the stored inks (#4945's native path) psd-tools posterize_16bits_cmyk goes from 4.26 % to 0.01 % of pixels off. 8-bit Posterize is unchanged. The GPU kernel runs the same rule; 16-bit layers reach it as half floats, so a sample within their precision of a bin edge can land in the neighbouring bin there (the CPU, which exports, is exact). psd-tools 239 -> 241; floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Groups: a pass-through clipping base with an adjustment renders isolated A pass-through group composites its children straight into the backdrop, so an adjustment layer inside reaches the layers beneath. When the group is the base of a clipping group and holds an adjustment layer, Photoshop renders it isolated instead: in psd-tools passthrough_clipping_mask_adjustment an Exposure in such a group leaves the layers beneath alone (we darkened them: half the image 170 levels off). The same group with a Linear Dodge child and no adjustment keeps reaching the backdrop (passthrough_clipping_mask_blendmode), and so do clipping-mask3/4/5, so the rule is the adjustment, not the clipping alone (isolating every pass-through clipping base broke those two). CPU compositor and GPU plan alike. psd-tools 239 -> 240; floor 240.

Layers panel: Clip Thumbnails to Layer Bounds (#4281) (#4312)
* Layers panel: Clip Thumbnails to Layer Bounds (#4281) Add interface.clipThumbnailsToLayerBounds (off by default), toggled from the Layers panel menu or Preferences > Interface.

Empty or fully off-canvas layers keep the canvas frame. The frame is computed only when the thumbnail is rebuilt (tile-cached content bounds) and is part of the cache key, so toggling rebuilds it.

Exact on every pixel of psd-tools threshold_rgb (36432 px; Rec. 601 split 28 the other way), threshold_16bits_rgb (100) and threshold_16bits_ grayscale, and the photoshop corpus's rgb16 threshold-128. The sums are exact in f32, on the CPU and in the GPU kernel, so ties (grey exactly on the level) split the same way on both. psd-tools: threshold_rgb and threshold_16bits_rgb pass; corpus test 239 -> 241, floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Posterize: 16-bit documents bin the 16-bit sample, as Photoshop does At 16 bits Photoshop doesn't round to 8-bit levels before binning. It bins the 16-bit sample, floor(v16 * n / 32768), and lands on 8-bit levels through a 16-bit step: floor(b * 32768 / (n - 1)), converted with floor((o * 255 + 16384) / 32768). So the middle of 3 levels is 128 where 8 bits give 127, while 42.5 and 25.5 stay 42 and 25. Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges. The same rule applies to CMYK and Lab channels at 16 bits: on the stored inks (#4945's native path) psd-tools posterize_16bits_cmyk goes from 4.26 % to 0.01 % of pixels off. 8-bit Posterize is unchanged. The GPU kernel runs the same rule; 16-bit layers reach it as half floats, so a sample within their precision of a bin edge can land in the neighbouring bin there (the CPU, which exports, is exact). psd-tools 239 -> 241; floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Groups: a pass-through clipping base with an adjustment renders isolated A pass-through group composites its children straight into the backdrop, so an adjustment layer inside reaches the layers beneath. When the group is the base of a clipping group and holds an adjustment layer, Photoshop renders it isolated instead: in psd-tools passthrough_clipping_mask_adjustment an Exposure in such a group leaves the layers beneath alone (we darkened them: half the image 170 levels off). The same group with a Linear Dodge child and no adjustment keeps reaching the backdrop (passthrough_clipping_mask_blendmode), and so do clipping-mask3/4/5, so the rule is the adjustment, not the clipping alone (isolating every pass-through clipping base broke those two). CPU compositor and GPU plan alike. psd-tools 239 -> 240; floor 240.

Pen tool: Shift constrains segments and handles to 45° (TOOL-214-10, #3751) (#3756)
* Pen tool: Shift constrains segments and handles to 45° (TOOL-214-10, #3751) Shift-click puts the next Pen anchor on the nearest 45-degree ray from the previous anchor (at the pointer's projection onto it); Shift held while dragging out direction handles turns them to 45-degree steps, read live per move. The first anchor, closing on the first anchor and the last-anchor break are unaffected; after Alt breaks the pair Shift constrains the outgoing handle alone. The rubber band previews the constrained point. Reuses stroke_constraint::snap45. Flips scorecard TOOL-214-10 to done.

Brush Settings: a response curve per dynamic control (#3294) (#3302)
* Brush Settings: a response curve per dynamic control (#3294) Every brush Dynamic (Size, Opacity, Flow, Roundness, Scatter, Count, Depth, Foreground/Background...) now carries its own response curve for its control (Fade, Pen Pressure, Pen Tilt, Stylus Wheel, Rotation), applied after the global Preferences pen curve. It is part of the brush JSON, so tools.setBrush sets it (e.g. shapeDynamics.size.curve), actions record it and presets keep it; linear by default, so existing brushes paint unchanged. - paint: ResponseCurve, the global pen curve's monotone cubic moved down from the engine as a fixed-size Copy type (no allocation per dab); serialises as its point list. dynamics::dynamic_value applies it. - engine: prefs::PressureCurve is now that type. - ui-egui: each Control row gets a curve button (lit when the curve isn't linear) that shows the same editor as Preferences > Tools. - scorecard: TOOL-213-11 done.

Brushes: import an image file as a brush tip (#3279) (#3292)
* Brushes: import an image file as a brush tip (#3279) `brush.presets.importImage` reads an image (path, or base64 data with an optional fileName) through the normal importer, so any format and bit depth File > Open reads works. Its composite becomes a sampled tip the way Define Brush Preset reads a selection: darkness x alpha, cropped to the painted extent, at most 2500 px a side. The bounds are found band by band first, so a large mostly-white image never needs a full-size buffer. The preset is named after the file (never replacing an existing one) and becomes the current brush unless select is false. Import Brushes... in the Brushes panel and the brush preset picker now opens a picker for .abr and image files; images go to the new command, .abr files to brush.presets.importAbr as before. Automation refuses an ambient `path` for it like the other import commands. Define Brush Preset and the new command share `sampled_brush`. Scorecard TOOL-213-12 -> done.

Layers panel: filter-type dropdown with Kind, Name and Mode (#5048) (#5268)
The filter row's "Kind" was painted text. It is now a dropdown, as in
Photoshop: Kind keeps the five layer-kind toggles, Name lists layers whose
name contains the typed text (ignoring case), and Mode lists layers with
one blend mode (Pass Through included), filtering by Normal at first.
The criteria live in UiState (layer_filter_by, layer_filter_name,
layer_filter_mode; serde defaults, so saved settings still load) and are
drivable with ui.set {layerFilter: {by, kinds, name, mode}}, validated
before anything changes. ui-parity.md gets a partial row: Effect,
Attribute, Color, Smart Object, Selected and Artboard are still missing.

Free Transform: the box is the selection, and the marching ants follow it (#5297) (#5337)
With a selection, ⌘T and the Move tool's Show Transform Controls framed the layer's content clipped to the selection, so the box was smaller than the marching ants wherever the layer did not fill the selection. The ants then stayed where the selection started until the transform was applied. - transform_frame / target_frame (engine): the box is the selection's own bounds when a selection limits the transform. transform_bounds is unchanged, so snapping and the command defaults are as before. - The selection outline is drawn through the open box (homography, or the warp in Warp mode), so it follows move, scale, rotate, skew, distort, perspective and warp before the transform is applied. The whole outline is traced while such a box is open, not only the part in view where it started. - marching_ants_lines: ants along screen-space lines; non-finite lines are skipped and very long ones are clipped to the view. Part of #3402. Claude-Session: https://claude.ai/code/session_015vKPoMXFhSvWmX5D9XM646 Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> Co-authored-by: Brandon Thomas <echelon@gmail.com> |

32-bit: legacy Brightness/Contrast, Channel Mixer, Photo Filter and B&W tint unclipped, as in Photoshop (#5011)
* 32-bit: legacy Brightness/Contrast, Channel Mixer, Photo Filter and B&W tint unclipped In 32-bit documents Photoshop keeps these adjustments' results above 1 and below 0. On the photoshop corpus's rgb32/gray32 files: - Legacy Brightness/Contrast pivots its contrast at 127 of 255 (8/16-bit: 128) and is exact on every pixel. - Channel Mixer cuts each source percentage to 1/1024 toward zero, counts 255/512 of the constant and is exact on pure red, green, blue, black and white. - Photo Filter works on the linear samples, negative results included. - The Black & White tint is the Color blend mode without the clip at 1, as the blend mode is there; white tints to (1.05, 1.00, 0.87). We clipped all four to 0..1. The GPU kernels follow suit under F_HDR (the legacy pivot and the mixer's steps come from the planner), and the HDR parity test covers them. Photoshop oracles: rgb32 and gray32 brightness-contrast-legacy, rgb32 channel-mixer and black-white-tint pass (145 -> 149 of 258); floor 145 -> 149. rgb32 photo-filter improves (0.19 -> 0.035 max); the rest is its colour (#3790). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Masks: feathers blur with exactly the feather's variance A mask feather is a Gaussian with sigma = feather, which we approximate with three box passes per axis. Whole-pixel boxes rounded the variance: a 6 px feather blurred like 6.48 px and a 3 px one like 3.46 px, so feathered edges were too soft by up to 4 levels against Photoshop (psd-tools mask-parameters-no-real-channel.psd: a 6 px vector and 3 px pixel feather). Each pass is now an "extended box" (Gwosdek et al. 2011): weight 1 on the whole radius and a fractional weight on the two samples beyond it, so three passes have variance sigma^2 exactly. It stays O(n), reusing the window's leaving sample for the low end weight (50 MP at a 1000 px feather: 180 ms parallel, was 172). psd-tools: mask-parameters-no-real-channel 0.0168 -> 0.0060 (PASS), layer_mask_data.psd 26.9 % -> 3.9 % of pixels off (psb 25.9 % -> 1.8 %).

Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges. The same rule applies to CMYK and Lab channels at 16 bits: on the stored inks (#4945's native path) psd-tools posterize_16bits_cmyk goes from 4.26 % to 0.01 % of pixels off. 8-bit Posterize is unchanged. The GPU kernel runs the same rule; 16-bit layers reach it as half floats, so a sample within their precision of a bin edge can land in the neighbouring bin there (the CPU, which exports, is exact). psd-tools 239 -> 241; floor 236 -> 241. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * Groups: a pass-through clipping base with an adjustment renders isolated A pass-through group composites its children straight into the backdrop, so an adjustment layer inside reaches the layers beneath. When the group is the base of a clipping group and holds an adjustment layer, Photoshop renders it isolated instead: in psd-tools passthrough_clipping_mask_adjustment an Exposure in such a group leaves the layers beneath alone (we darkened them: half the image 170 levels off). The same group with a Linear Dodge child and no adjustment keeps reaching the backdrop (passthrough_clipping_mask_blendmode), and so do clipping-mask3/4/5, so the rule is the adjustment, not the clipping alone (isolating every pass-through clipping base broke those two). CPU compositor and GPU plan alike. psd-tools 239 -> 240; floor 240.

Posterize: 16-bit documents bin the 16-bit sample, as Photoshop does (#5267)
At 16 bits Photoshop doesn't round to 8-bit levels before binning. It bins the 16-bit sample, floor(v16 * n / 32768), and lands on 8-bit levels through a 16-bit step: floor(b * 32768 / (n - 1)), converted with floor((o * 255 + 16384) / 32768). So the middle of 3 levels is 128 where 8 bits give 127, while 42.5 and 25.5 stay 42 and 25. Exact on every sample of psd-tools posterize_16bits_rgb (levels 3, 7, 13, 21) and posterize_16bits_grayscale (2, 6, 9, 11); the 8-bit rule missed up to half the range at bin edges.

ACEScg: File Handling option opens colour-less EXR renders in the ACES working space (#4908)
* ACEScg: File Handling option opens colour-less EXR renders in the ACES working space Our render pipelines write ACEScg (AP1 primaries, ACES white ~D60, linear) and — like most — state no colour space in the EXR header, so io's linear-sRGB default misrepresented them (saturated hues shifted). - cms: AcesCg joins the built-in profiles, generated from the published AP1 primaries and ACES white point with a linear TRC (id "aces-cg", aliases acescg). - engine: File Handling gets "Open color-less EXR as ACEScg". When on, an EXR that io tagged with the linear-sRGB default opens as ACEScg instead; embedded or EXIF-declared profiles stay untouched. Translated in every catalog. ACES view transforms (OCIO-based display) remain future work; this covers the document's source colours. * scorecard: 26 of 158 (main's #3472 preference added one too) * Regenerate docs/scorecard.md after merging main --------- Co-authored-by: Brandon Thomas <echelon@gmail.com> |

Linux: a virtual keyboard claiming BTN_TOOL_PEN no longer sends the window through Xwayland (#5284) (#5295)
* Linux: a virtual keyboard claiming BTN_TOOL_PEN no longer sends the window through Xwayland (#5284) On Wayland the app opens its window through Xwayland when a pen is attached (#639), and it took any input device whose key bitmap has BTN_TOOL_PEN for a pen. A virtual keyboard made with uinput (RustDesk's, for one) claims every key code, that one included, so the window went through Xwayland on machines with no pen at all. On a fractionally scaled desktop (GNOME 46 at 125%) the X11 window is drawn at the logical size and upscaled by the compositor, so the UI came out blurred even though Auto UI Scale already followed the system's 1.25 (#1237): native Wayland, where winit negotiates wp_fractional_scale_v1 and renders at the physical 3840 px, was never used. A pen now also needs ABS_X and ABS_Y in its absolute-axis bitmap, as libinput asks of a tablet tool; a keyboard has no axes. Regression tests with the virtual keyboard's own bitmaps, a pen beside it, and a pen display. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> * Docs: on a fractionally scaled Wayland desktop, Xwayland is blurred and native Wayland has no file drops (#5284) Say where the trade-off is: a native Wayland window is sharp at 125%, 150% and 175% but takes no dropped files (#386); an Xwayland window takes drops and pen input (#639) but is enlarged by the compositor.

feat(commands): find the Elliptical Marquee by 'ellipse' or 'marquee' (#5140)

Commands can now carry search keywords. command.list / engine.commands rows include them as "keywords", and the three filters (CLI commands --filter, the engine.commands RPC and the MCP command_list) share one matcher over id, label and keywords. select.rect gets the Photoshop marquee names as keywords. * Command list replies: document the optional keywords key The reply-shape test from #3684 pins the exact keys of each row; select.rect now also carries keywords, so the test and docs/control-protocol.md allow that one optional string. |

Gradient Map is driven by the W3C luminosity, as in Photoshop (#5018)
Photoshop's Gradient Map picks each pixel's place on the gradient by 0.3 R + 0.59 G + 0.11 B, the luminosity of the blend modes. We used the Rec. 601 grey (0.299, 0.587, 0.114). That is a few thousandths off, but it is enough to land two levels away on steep stretches of a gradient. The photoshop corpus's rgb8 and rgb16 gradient-map.psd now pass (they were 2 levels off on 0.8-1.7% of pixels). Sampling the gradient through a 256- or 1024-entry table didn't help; the weights did. CPU (compose::adjust) and GPU (the shader's lum) both change. Lab documents keep their Gradient Map driven by L, and grey pixels map as before. Photoshop oracles 145 -> 147 of 258; floor 145 -> 147.

PSD: Mt16/Mt32 blocks mark the merged image's transparency (#5178)
The merged image carries its transparency in the first extra channel when the layer count is stored negative, or when a "Saving Merged Transparency" global block (Mtrn, Mt16, Mt32) is present. Photoshop saves 32-bit documents the second way: a positive layer count, Mt32, and a fourth channel named "Transparency" (psd-tools transparentbg). merged_has_alpha only knew the first, so opening such a file added a "Transparency" alpha channel to the document, and the oracle compared it as if it were opaque white (83.7 % of pixels off; now 0.9 %, all on the shape's edge).

Stroke latency trace: PHOTOCRAFT_STROKE_TRACE times each frame of a brush stroke (#1343) (#4403)
Testers report ~50 ms input-to-pixel while painting on Linux and macOS, and asked for a per-stage breakdown. With PHOTOCRAFT_STROKE_TRACE=1 the app prints, per stroke, p50/p95 of the frame interval, pointer moves per frame, the live stroke's render, the canvas refresh (composite + upload), the UI build, eframe's CPU time (UI, tessellation, submission) and the remaining vsync/swap-chain wait, with the GPU backend; =<file.csv> also appends every frame. The last summary is in the control channel's perf.strokeTrace. RTX 5090, Vulkan, 120 Hz: interval 8.33, cpu 2.2 (ui 0.9, stroke 0.8, canvas 0.4), wait 6.0 ms. |

Blur Gallery: Field Blur pins on the image (#3373) (#3801)
* Blur Gallery: Field Blur pins on the image (#3373) Field Blur opened a parameter dialog with one centre, though the engine already blends any number of pins. It now works as Photoshop's Blur Gallery workspace: the image under the dialog takes the pointer. A click adds a pin and selects it, a drag moves a pin, and a drag around the selected pin's ring turns its blur up or down (one turn is the 0-500 px range; the arc shows the amount). Delete or Backspace removes the selected pin. The dialog shows the selected pin's Blur and Preview, and opens at the right edge, beside the image, so the pins stay in view. The pins live in the dialog's fields (`pins`, `__selected`), so the existing filter preview follows every change, OK applies filter.blurGallery.fieldBlur with them in one step, and automation drives it with ui.dialog.set. Pins are fractions of the selection's bounds when there is one, else the canvas, as the engine reads them. Proxy previews now scale Blur Gallery pins' pixel blur like other pixel params.

Brush: remember the last selected brush across restarts (split from #2516) (#3472)
* Brush: remember the last selected brush across restarts (split from #2516) The persistence half of #2516 on its own, so it can merge and be maintained apart from the brush-outline half. The tool's brush (settings, tip references, and the name of the preset it was picked from) is saved once the pointer is up and restored at launch: options bar, painting cursor and Brushes panel highlight all start where the session left off. Review fix from #2516 -- no per-frame work: - `ToolState::brush_rev` is bumped by every brush/preset setter (`tools.setBrush`, preset save/delete/rename/setCurrent/deleteGroup, `brush.defineFromSelection`, `brush.presets.importAbr`, the store's tip re-linking, and the shell's tool-switch/reset paths); `remember_brush` serialises only when it moved since `brush_saved_rev`, so an unchanged brush costs a counter compare per frame, not a clone and a JSON dump of the whole brush (sampled tip previews included). - Restoring counts as saved: the launch value is never rewritten. Bitmaps stay out of the preferences document: remembered tips and patterns are references (a loaded stored tile drops its full bitmap), and a sampled bitmap too big to embed is skipped, keeping the previous value so a preview never enters the prefs file. A malformed remembered brush falls back to the default. docs/scorecard.md regenerated with `cargo xtask scorecard` (34 of 154). Tests: engine 1267 lib (5 new: revision gating, rejected changes, picked preset, restore round trip, no embedded bitmaps), ui-egui 1982 lib; clippy, layers, wasm green. * rustfmt the StoredTile line and regenerate the scorecard after the main merge * engine tests: destructive Levels keep the signed float overshoot at 32 bits (#2592) * Scorecard: regenerate after merging upstream/main * Export As: compare batch paths without the Windows separator * font fix ? * fix(ui): only Filter menu dialogs get the in-dialog preview window #3877 drew the preview window in every schema dialog with a Preview checkbox, including Image > Rotation > Arbitrary. Photoshop's Rotate Canvas and adjustment dialogs have no preview window, and the taller dialog covered the canvas, which broke arbitrary_rotation_preview::size_changing_rotation_preview_is_visible_and_preserves_the_panned_center on main.

fix(type): missing-font checks follow layout's PostScript resolution; split hyphenless style suffixes (#608)
* fix(text): split hyphenless PostScript style suffixes
A PostScript name without a hyphen kept its style in the guessed family:
`GmarketSansBold` became the family "Gmarket Sans Bold" at weight 400.
The guess now drops a trailing capitalised style word (Gmarket Sans, 700).
A lowercase ending ("Daylight") is not a style, and a style word after the
vendor tag MT stays in the legacy family ("Arial Rounded MT Bold").
Hyphenated names keep the last-hyphen parsing from #3878.
PSD import stores this guess when the exact face is absent. A legacy family
that ends in a style word without MT before it ("CooperBlack") is stored as
the shorter family (Cooper, 900) until the face is installed.
Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
* fix(type): missing-font checks follow layout's PostScript resolution
When a run's stored family is not installed, layout draws it with its exact
PostScript face, or with the family guessed from that name if installed.
Missing-font detection compared only the stored family label, so such a run
was reported missing, and Replace Missing Fonts rewrote it whenever an
unresolved run shared the label. missing_fonts, missing_fonts_in_layer and
the replacement now use layout's decision.
#1406 already corrects the label when a PSD or Affinity file is opened with
the face installed, and #1844 finds exact faces outside the family prefix.
The label still stays on a run reopened from .pcraft after its font was
installed, on fonts that arrive after opening, and on a run created with
both "font" and "postscriptName". The tests take the .pcraft and command
paths.
