The WebP chunk walk added the chunk length to the offset without a
checked add, so a length near u32::MAX overflowed on 32-bit targets
(wasm32) with overflow checks on. It now reads the chunk through the
same checked slice helper as the PNG, JPEG and TIFF readers.
This reverts commit bada8e1710. #7638 merged with its gate failing: besides six unformatted
files, render and trace don't compile against craft-libs e2dc681 (u64::from(usize) in
render/src/paint.rs, a private craft-libs function, and a call with one argument too many in
trace/src/opaque.rs), so main's CI fails. The tree is that of 0adbdce6cb, whose CI passed.
When a Type 2 CIDFont or a Type 42 descendant of a composite font has no FontMatrix, the
font a cshow procedure sees as current now takes the identity as its default, as glyph
measuring and drawing do, instead of the 1/1000 default of other fonts.
Measuring an instance of a symbol with 9-slice guides looked its map up
through Document::symbol_slice_map, which scanned the symbol list and
measured the art box again in new quick boxes, and NineSliceMap::place
and most_placed made new quick boxes of their own. Each of those boxes
built the symbol name index over the whole list on its first lookup, so
every 9-slice instance measured read every symbol once or more. Picking
an object inside a 9-slice instance's art with Direct Selection did the
same for each object of the art that holds a symbol instance.
- SymbolBoxes cuts the guides through the art box it has measured
(SymbolBoxes::slice_map), and places and counts the art with itself as
the boxes, in the mode quick boxes use. Art with no 9-slice map is
moved by the instance's transform without looking the map up again.
- Document::symbol_slice_map, place_symbol_art,
place_symbol_art_unclipped and edited_nine_slice use one set of quick
boxes for each call.
- symbol_part_at and symbol_part_outline keep one set of quick boxes
for the instance's art.
The new tests count the symbols read. Measuring 200 instances of a
symbol with guides and 200 of a symbol with guides holding it, among
2,002 symbols, read 1,205,204 symbols before; now each set of boxes
reads the list once. Picking in a 9-slice instance whose art holds 20
instances read 84,042 symbols among 2,001; now it reads the list at
most twice.
With a Type tool and exactly one character selected, the canvas shows up
to five of that character's alternate glyphs in a row beside it. A click
runs the command the Glyphs panel's double-click runs, as one undo step;
an arrow at the end opens the Glyphs panel on Alternates for Current
Selection when the character has more. Preferences > Type > Show
Character Alternates (showCharacterAlternates, on by default) turns the
row off.
An image or a gradient mesh with a visible Crop Marks effect, or with a
Vector Halftone effect that makes dots, is measured in a plot of the art's
bounds. A halftone that makes no dots, such as one past the effect's cell
limit, leaves the image out as before.
