M13.5: stroke taper/wave/multi-dashes, radial gradient highlight, variable-width mask feather, adaptive motion-blur samples

Shapes (SHP-2): Stroke Taper (pixels/percent start/end length, width, ease) and
Wave (amount, pixels/cycles, wavelength, phase) rendered as a variable-width
outline; Dash 2/Gap 2/Dash 3/Gap 3 (shape.dashes.add/remove, timeline +/-
buttons); radial gradient Highlight Length/Angle as a focal gradient.
Masks (MSK-1): mask feather points on the Mask Path (mask.featherPoint.*,
Mask Feather tool add/drag), per-point signed radius and tension, rendered
from the signed distance to the path; carried through vertex edits.
Motion blur (LYR-10): Adaptive Sample Limit comp setting; 2D layers take one
sample per pixel of shutter travel between Samples Per Frame and the limit.
