commit 50254a7fb41507fde353081cab5020de41389db0 Author: Jia Yu <[email protected]> AuthorDate: Wed Mar 4 18:09:09 2026 -0800 [GH-2678] Add SVG visuals for affine transformation functions (Phase 8) Add overlay-style SVG illustrations for all 7 affine transformation functions showing input geometry (blue dashed) and transformed result (green solid) in the same coordinate space: - ST_Affine: horizontal shear transform - ST_Rotate: 45 degree counter-clockwise rotation around centroid - ST_RotateX: 3D rotation around X-axis (Y compression in 2D projection) - ST_RotateY: 3D rotation around Y-axis (X compression in 2D projection) - ST_Scale: non-uniform scaling (1.5x, 2y) from origin - ST_ScaleGeom: scaling relative to centroid (0.5x, 0.75y) - ST_Translate: translation by (deltaX=2, deltaY=1.5) Image references inserted into all 3 doc variants (SQL, Flink, Snowflake).
