vangel76andClaude Opus 5.5 d37c087975 Transform effect: skew after the rotation and drawn outside the layer, as After Effects ...

After Effects draws the Transform effect as position + K * R * S * (p - anchor)
with the skew K = rot(-axis) * shearY(tan skew) * rot(axis) applied after the
rotation, and keeps what lands outside the layer's bounds. EffectCraft skewed
before rotating (shearX about the axis) and clipped to the layer.

Measured in AE 2026 on a grey 960x540 solid (cases 723, 819, 820): 723 (anchor,
position, scale 120/80, skew 10 axis 20, rotation 30, opacity 70) differed in
11.25 % of the frame and now in 0.065 % (edges, max 16/255), CPU and GPU alike;
819 / 820 (skew 15 axis 60, rotation -25, scale 130/70, anchor) match to the
edge. The buffer grows on each side by that side's overshoot (also for the
motion-blur samples), capped at 16 384 px a side and 16 Mpx in all so a layer
moved far away costs a bounded allocation (regression test); adjustment layers
keep their size.
