   Bug 801: Graph TextRenderer Cleanup Part-1a (unclean)
    
    Remark: This commit is unclean and requires 'Part-1b' due to
            merging this commit after more than 2 years!
    
    Graph:
      - Use List<OutlineShape> instead of array
        allowing more flexible memory managment.
    
      - GLRegion -> Region promotion:
        - Region create(List<OutlineShape> outlineShapes, int renderModes)
        - Region create(OutlineShape outlineShape, int renderModes)
    
      - Region additions
        - void addOutlineShape(OutlineShape shape)
        - void addOutlineShapes(List<OutlineShape> shapes)
    
      - RegionRenderer
        - draw(..) remove 'position', redundant
        -
    
      - Deprecate 'TextRenderer' and 'GlyphString'
        Use Region.create(Font.getOutlineShapes(...)) + RegionRenderer instead.
    
      - FontInt -> Font promotion (make public)
        - getOutlineShape and getOutlineShapes
    
      - Font.Glyph additions
        - 'getID(), hashCode()'
        - 'float getScale(float pixelSize)'
    
      - GlyphShape
        - Add reference to Glyph allowing GlyphString
          to access the font metrics for translation and scaling
    
        - Experimental pre-scale/translation in GlyphString
          using default font size and it's metrics

  Bug 801: Graph TextRenderer Cleanup Part-1b (clean)
    
    Concludes commit f51933f0ebe9ae030c26c066e59a728ce08b8559
    w/ final fixes on merge commit 3352601e0860584509adf2b76f993d03893ded4b.

0af9df19efc3bc31beafdd63e3487b74a97c80a7
  Performance Note: ~800-1200 fps on uncached text line


Notable:
  - Enhance Graph core data management (OutlineShape/GLRegion)
  - Reduce data copy and regeneration
  - Enhance text rendering w/ typecast
  - Code cleanup

  - Add frustum culling to GLRegion

  - Test diff AA methods
    - MSAA
    - VBAA (brute-force, Flipquad, RGSS, Quincunx, FXAA2)
        - brute-force >> flipquad > rgss >> quincunx
        - FXAA2 not suitable

  - Shader Management
    - Switch shader instead of branching in shader (performance)

    - Use common shader-stubs for pass-1 and pass-2, 
      assembled in RegionRenderer.useShaderProgram(..)

    - Support regions w/ shaders for
      - plain
      - color textures
      - texture sequence (e.g. GLMediaPlayer)

  - GraphUI
    - Use Quaternions
    - Use Ray picking
    - Add Texture- and MediaPlayer-Button

This cleanup stage is completed.

Eventual changes in core and/or use-cases
will be referenced in a follow-up bug report.
