Graph/GraphUI: Revise Graph Region ShaderMapping, fix AABBox-Clipping for 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()
