The EPS interpreter counted one operation against its budget for each
name it ran, whatever the operator did, and paths had no length limit.
Parsing one arc at a radius of 10^300 passed 3 GiB of resident memory
within 43 seconds. A loop of arc at a radius of 2.2 x 10^18 was still
running after 60 seconds, and a loop of pathbbox on a path of 100,001
elements and { {} loop } loop did not finish within 20 seconds. PDF
content had no path limit either: parsing a page that repeats
0 0 1 1 re 4,000,000 times peaked at 2.3 GiB of resident memory.
A path now holds at most 1,048,576 elements (MAX_PATH, the limit of
VectorCraft's EPS interpreter). In EPS, moveto, lineto, curveto,
closepath, arc, charpath and the rect operators check it, and an
operator that would take a path past it stops the program with
"PostScript (path limit)". In PDF, m, l, c, v, y, h and re (each adds
at most five elements) stop the content stream with
"content (path limit)" when the path already holds more than 1,048,571.
Each path element an operator makes, reads or copies (arc, rectangle
arrays, charpath, pathbbox, clip, eoclip, gsave, save) now counts
against the EPS budget. Each pass of repeat, for, loop and forall
counts too, and so does each procedure item that is not a name. A
moveto right after a moveto replaces it, as the PostScript Language
Reference describes, so text placed with moveto and show leaves one
element.
Five tests in tests_import.rs cover the loops, the path limit in both
interpreters and runs of moveto and show.
- Keyboard Shortcuts: Enter is not Delete while the delete confirmation is open (#1113 with #1019).
- Speed graph drag test compares proportions, since the Graph Editor now fits its selection (#1182 with #1109).
- Spanish panel test no longer demands the Chinese catalogs' exact rows (#996 with #1189, #1019).
- Object Matte gets its Simplified Chinese effect-name row (#1199 with #792).

- Cryptomatte (#1183): planes shorter than the image read as empty instead of panicking.
- layer.addMarker (#1180): a comp marker no longer replaces one at the same time.
- Desktop (#1005): ignore macOS's -psn_ argument instead of refusing to launch.
- Doc comments put back on their own items (#1153, #1037).

The six PSD PRs merged one by one leave #1131's test calling samples()/to_rgb(), which #1139
replaced; vangel76's integration draft #1149 has the adapted version.

The nightly FreeBSD run measured 119 ms/frame against a 100 ms limit: the mean included
Tracker::new and any scheduling stalls on the two-core VM. The best single step with a
250 ms bound still catches an order-of-magnitude regression.
