Graph Clipping: GLSL: Add `USE_AABBOX_CLIPPING`, i.e. clipping via AABBox min/max vec3 as convenient using Graph/GraphUI produced AABBox

USE_AABBOX_CLIPPING
- Conditional compilation w/ macro 'USE_AABBOX_CLIPPING'
- gcv_ClipBBoxCoord smooth varying setup in vertex shader
- fragment shader clips via branch
    if( is_inside(gcv_ClipBBoxCoord, gcu_ClipBBox[0], gcu_ClipBBox[1]) < 0.5 ) { CLIP }
- clipping via discard or alpha=0 in case of buggy-discard.

Other optimization:
- Drop gcv_ColorTexExt, fragment-shader uses gcu_ColorTexBBox[2] directly (flat)
- Simplified gcv_ColorTexCoord smooth varying equation in vertex shader.
