Culling a layer asked for its paint bounds, which walk its whole subtree,
and then did the same for each child: every layer's subtree was walked
again at each level above it, and once more in each parallel band. The
bounds worked out during a render are now kept for it (layers with
children only; bounds the 64-level cap cut short are not kept, and kept
ones are read only where their levels still fit under the cap, so culling
is exactly as before).
Every render also looked through every layer of the document for the
largest background blur, to size the overlap of its bands: 900 000 layers
on one large file, on the main thread before the bands start. The
document now works it out when first asked after a change, like whether
it has masks.
A 1440x900 render on a 900 000-layer file, page of 118 358 layers: at
100% 13.0 -> 0.6 ms, at 25% 16.5 -> 3.4 ms, fitted to the page 56 -> 31 ms;
page of 246 204 layers: 12.6 -> 2.5 ms, 12.1 -> 2.0 ms, 69 -> 62 ms.

- Cursors: the engine names a cursor for every tool, modifier and hover
target (rotate turned to its corner, pen states, eyedropper, comment,
copy on Alt, not-allowed while an instance refuses the edit); the UI shows
the system's or draws its own; guides and handles keep their cursors;
ui.inspect reports it.
- Panels: each edge drags its panel within limits, a double-click resets,
widths are per window and kept in the preferences (view.panelWidths); a
small window keeps its canvas.
- Outline mode: Include hidden layers and Include object bounds
(view.outlinesHiddenLayers, view.outlinesObjectBounds), drawn and
clickable; light lines on a dark page; check marks in the View menu.
- A file or page made in the dark theme has a #1E1E1E page (sessions
without an interface keep #F5F5F5); text drawn on a dark page is white.
- Tests for Enter and Escape on a selected text.
Text layers can follow a path (start offset, flip, alignment; edited in place; canvas, PNG, SVG, PDF; SVG textPath imports as real text on a path). A new pattern paint tiles a source layer in grid or hex rows with scale, spacing and alignment, live as the source changes (SVG pattern, PDF vector tiling pattern).
