A vector's corner smoothing was stored, imported and exported, but its
rounded points were drawn as plain circular arcs, and the Design panel
hid the Corner smoothing control for vectors.
A vector with a closed region now draws its rounded points with the
layer's corner smoothing, on the canvas, in hit testing, in PNG, SVG and
PDF exports, and in the fill and stroke geometry of .fig exports. Each
point keeps its own radius; a point without one stays sharp. The corner
uses the profile of smoothed polygon corners, and smoothing is reduced
before the radius when a corner does not fit in half of each segment.
FigCraft's own rules for cases the help page does not describe: only a
point between two straight segments that both bound a closed region is
smoothed; points on open branches and points next to a curved segment
keep the plain arc; concave corners are smoothed like convex ones.
The Design panel shows Corner smoothing and its iOS (60%) button for
vectors with a closed region, and not for open paths.
Merging every region of one stroked shape is a no-op again: only fill
parts count, so a vector with several painted regions still merges.
The region paint import budget now covers the whole file instead of
resetting for each layer, so instances of a main with large region paint
stacks cannot multiply the work.
