Conflicts were main's new code next to this branch's additions; both kept:
- crates/effects/src/lib.rs: main's Buf::pad_sides stays as main wrote it
(Transform's transform_grow bounds that padding itself); Buf::pad keeps
this branch's effective-pad clamp.
- crates/raster/src/lib.rs: main's quantize_px/round_half_up and this
branch's MAX_PADDED_SIDE (still equal to limits::MAX_SIZE on main).
The camera's Set Focus Distance to Layer command compared only 'd <= 0.0', which NaN passes, and two finite but extreme positions can overflow their difference to infinity; a stored non-finite focus distance serializes as null and leaves the project unsavable. Reject it, fall back to the zoom plane in the camera evaluation, and count a non-finite focus or depth as in focus. The Classic 3D blur radius itself was unbounded: a 0%-scaled or very distant layer scales it by up to 1e9, and the padded blur buffer sized from it aborts the process. Cap each plane's radius to a padded buffer that fits the renderer's 16 Mpx layer budget, don't blur planes whose pixels cover under a thousandth of a comp pixel, saturate the padded sizes, and refuse padded buffers past the project's maximum layer size. Regression tests for each guard.
- gpu: pooled working textures (released once every encoder that could read
them is submitted), shared zero images, reused readback staging buffers,
direct readback into Image; NaN-poisoned scratch images under test and
NaN-aware diffs; validation errors panic under test
- render: AutoPick (per comp / scale / path EWMA of CPU vs GPU frame times,
warm-up and periodic re-probe) behind Backend::Auto; viewer uses it too;
cached adjustment footprints (uploaded once)
- gpu fx_warp: Warp, Bezier Warp, CC Bend It, CC Page Turn, Smear, Reshape,
Color Emboss, Cartoon; sliding-histogram median for large radii; CC Power
Pin perspective < 100
- cli: bench --gpu reports Auto and per-frame upload / readback MB

Planes prepared for the GPU carry their depth of field (padding, radius map, levels) and the
bokeh_boost / bokeh_prefix / bokeh_gather kernels blur them where they are drawn, with the CPU's
spans; GPU-vs-CPU agreement tests for iris shapes, highlights, fringe, Fast Rectangle, tilted
planes and a 2D layer with a 3D track matte.
