- Each segment of a pressure curve is also sampled where its width stops
rising or falling, so a dip between the regular samples of a long
curve is kept. The segment's values are scaled into -1..1 before that
is solved, so huge values in a file can't overflow it.
- A curve counts as full width only within 1e-9 of it, so a curve just
under full width keeps its profile.
- The pressure points of all strokes in one read are limited to about a
million, as for characters and table cells. Curves at full width count
too, and once the limit is reached no more curves are read; the
strokes past it are imported as plain strokes with a warning.
In Affinity Designer, Recolor Adjustment layers (RcRA) can be attached to
vector groups/shapes via AdCh. Lightness 1.0 recolors target elements to
white. Import visible RcRA layers as ColorOverlay effects and apply them
during node appearance evaluation.
