Frustum mapping + GraphUI Support
AABBox clipping naturally couldn't be transformed into 3D Model-View (Mv) Space,
as it is axis aligned and only provided 2 points (min/max).
Therefor we map the Group's AABBox to a 8-point Cube,
perform the Mv-transformation and then produce the 6-plane Frustum.
As before, we cull fully outside shapes within the Group's draw method
and perform fragment clipping with same Frustum planes in the shader.
With clipping enabled, the 3D z-axis getBounds() depth
will be slightly increased for functional Frustum operation.
This is also done for setFixedSize(Vec2f).
The Frustum planes are copied to the Graph shader
via float[4*6] -> uniform vec4 gcu_ClipFrustum[6]; // L, R, B, T, N, F each {n.x, n.y, n.z, d}

Pass2-AA, revise Pass2 AA Quality parameter ..
Misc:
- Graph VBORegion2PVBAAES2: Drop unused FBO rescale
- Move MIN/MAX QUALITY/SAMPLE from GraphUI Scene -> Graph Region
+++
Quality -> Pass2 AA Quality
- Drop quality field in region
- Pass quality to GLRegion.draw(..) similar to sampleCount
for dynamic shader and switch
- TODO: Pass quality parameter in TextRegionUtil's functions
Fix RegionRenderer Shader Mapping
- Use ShaderKey class to properly implement the hash value and equals method
- For this, TextureSequence.getTextureFragmentShaderHashID() has been added
to provide actual shader-snippet for the equals function
- All required criterias are included in the hash value and equals method
Fix AABBox Clipping for Pass-2 AA
- Clipping in pass2-AA must happen in pass2 on actual gcu_PMVMatrix01 (not ortho)
+++
GraphUI GraphShape
- Rename: [get,set]{->AA}Quality()
GraphUI Scene
- Rename: mark{All->}ShapesDirty(), set{AllShapes->}Sharpness(), set{AllShapes->AA}Quality()
- Fix setSampleCount(..), i.e. markStatesDirty() not markShapesDirty()
- Fix setAAQuality(), markShapesDirty() and markStatesDirty(): Use forAll(..) to traverse through all shapes and groups.
GraphUI Group
- Add setFixedSize()
- Add setClipOnBox()
- Document setRelayoutOnDirtyShapes(), isShapeDirty()

in shader; Update attributes and uniforms manually, drop ShaderState;
- ShaderCode
- add int insertShaderSource(int shaderIdx, int position, Class<?> context, String path)
- insertShaderSource(..): pos==-1 -> append code
- VectorUtil
- add isVec3InTriangle3(..., float epsilon)
- add testSeg2SegIntersection(..., float epsilon)
- add testTri2SegIntersection(..., float epsilon)
- AffineTransform: Return result for chaining
- Font
- Add pixel precise 'getPointsBounds(final AffineTransform transform, CharSequence string, float pixelSize)'
- Rename getString*() -> getMetric*()
- OTGlyph: Release _points field, no more used
-
- Graph Triangulation
- Count additional vertices in: Triangulator, CDTriangulator2D
- OutlineShape:
- Allow skipping of 'transformOutlines2Quadratic', i.e. allow tagging
OutlineShape to be quadratic_nurbs via 'setIsQuadraticNurbs()'
- Clarify cleanup ot outlines in same method 'cleanupOutlines()'
- Count additional vertices ..
- Graph Shader:
- Start splitting and segmenting shader code for:
- pass1 / pass2
- features, i.e. sampleCont, color-channel, ..
