A skinned shadow caster. Rasterized into every cascade with GPU vertex skinning, so an animated mesh casts its live pose rather than a static bind-pose proxy. jointMatrices is the same skinning palette the lit draw uses (16 floats per joint).

Optional
Optional: per-primitive morph deltas (only ΔPOSITION is used for shadows).
Number of morph targets (0/undefined = no morph).
Per-target morph weights, length = morphTargetCount.
