Bug 801: WIP 1/2 - Add color attribute; Switch Shader instead of branching 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, ..
