vectorcraft_testkit::temp_dir returns a bare path, so every engine test
that wrote into one left the folder in the system temporary folder.
- testkit: TempDir, a test's own folder made through temp_dir (same
private creation and ownership checks) under a tag no other TempDir in
the process uses, removed with its contents when dropped, also when
the test panics.
- Engine unit and integration tests hold a TempDir for the whole test
instead of calling temp_dir: graph, fileio, compare, journal, library,
shortcut set, spelling, store, web export, cancel, containers, build,
color settings, command sweep, font folder, removed font, model-based
and the font search fuzz.
- The DCS and swatch library tests' own helpers and the PDF editing
tests' shared vc-pdfedit-<pid> folder use a TempDir per test too.
- The font and link file search, store, color settings and font folder
helpers no longer delete the private folder temp_dir checked and make
it again with default permissions.
An image's own fill or stroke with Outline Object now follows the outline of
the image's pixels that are at least 50% opaque, traced from the alpha and
fitted with curves, instead of the image's frame. An image without
transparency, one whose pixels can't be read, one of more than 64 megapixels
or whose decoded pixels take more than 256 MB, and one whose outline would
need more than 100,000 anchor points keep the frame. An image with no pixel
at least half opaque gives nothing to paint. Images of more than 4 megapixels
are traced from their alpha averaged down to 4 megapixels, and an averaged
pixel that covers a pixel at least half opaque stays at least half opaque, so
thin opaque lines stay in the outline. Each outline is traced once for its
pixels, kept for the next redraw while those pixels are loaded, and dropped
after them; a second thread that needs the same outline waits for the trace.
- vectorcraft-trace: `decode_alpha` reads an image's alpha, and
`opaque_outline` traces it as Black and White mode at threshold 128.
- vectorcraft-effects: the reshaped image art uses it for rows whose first
effect is Outline Object; Convert to Shape rows keep the frame.
- Docs: docs/mcp.md, the Outline Object params text and an evidence line in
docs/target-app-parity.md. docs/mcp.md also says that Use Preview Bounds
takes in the shapes an image's fills and strokes paint.
- Drag strokes, fills, characters and effects to move them, or drop them
on the Duplicate or Delete button
- Select several rows with Shift/Cmd-click and move them as one block
- Delete and Backspace remove the highlighted rows, not the selected art
- Row links open their panel (Stroke, Character…) as a flyout
- Stroke weight spinner follows Units > Stroke
- Transparency panel edits the active fill's or stroke's opacity
Ungroup multiplied each member's opacity by the group's, so a member of a
50% group stayed at 50% after the group was gone, and members that
overlapped showed through each other. Each member now keeps its own
opacity, and the group's opacity is removed with the group.
