Brandon ThomasandClaude Opus 5.5 b3a980dcb5 Render: perspective shadows scale and skew about their alignment point
A shadow's sx/sy/kx/ky were applied about the shape's centre with the
skew unscaled, so a perspective shadow (algn=b, sy 23%, kx -20 deg) floated
in the middle of the shape instead of lying along its bottom edge. As
PowerPoint draws it, the shadow is skewed then scaled about the point of
the box its algn names (b: middle of the bottom edge, tl: top-left...).

Wild synthetic set: shadow alignment/scale/skew slide 5.57 -> 0.41,
picture frames 13.71 -> 12.71.
