Subject: Graph Clipping: Initial Region impl of AABBox clipping using GLSL
shader (Convenient using Graph/GraphUI produced AABBox)
Simple demo, setting clip-bbox manually:
- src/demos/com/jogamp/opengl/demos/graph/ui/UIShapeClippingDemo00.java
TODO:
- GLSL: Add missing Mv-multiplication of vertex-position -> gcv_ClipBBoxCoord
-- AABBox min/max should be set pre-multiplied w/ Mv covering an independent area, not per Shape/Region.
-- This to properly work with moving/scaling of each Shape/Region etc
