SweepDirectionVector extension
Provides the (non-normalized) 2D direction vector for each SweepDirection.
Vector components are -1, 0, or 1; diagonals are (±1, ±1) and so
are not unit-length. ShaderMaskTransition normalizes them before passing
uDirection to the GLSL shader. +y points down (Flutter screen space).
