Translating, rotating or warping content past the frame edge used to
smear the clamped edge row/column across the vacated region. The
transform, position, swirl, ripple and wave shaders now multiply the
sample by an in-bounds mask so off-frame pixels come out transparent
(and composite as black when nothing sits below). Tile deliberately
keeps its wrapping lookup.
21 built-in effects reimplemented as native GPU nodes from the
OpenFX-Misc algorithm references (cleanroom, docs in
docs/zh/plans/ofx-misc-gpu-cleanroom.md):
- Color: Color Correct, Gamma, Saturation, Invert, Clamp, Grade
- Matrix/morphology: Color Matrix, Edge Detect, Dilate, Erode
- Blur: Directional Blur, Sharpen (unsharp mask)
- Merge: Dissolve, Key Mix, Premultiply, Unpremultiply
- Geometry/generators: Position, Mirror, Checkerboard, Color Bars, Ramp
Every node carries unit tests plus GPU pixel tests (28 cases over five
ofxmisc_* suites). The effect library groups built-ins by category
(color/filter/distort/keying/generator/math/general) with collapsible
group headers persisted to the config; the inspector's add menu groups
the same way. Registration wiring and the factory smoke table land with
the adjustment/transition wave sharing the same files.
