Bug 802: Graph TextRenderer Performance Part-2 (fix artifacts, cleanup, incomplete)

- OutlineShape
  - Add DIRTY_VERTICES bit in triangulation,
    which in turn solves the rendering artifact issue.

  - transformOutlines(..) -> protected

  - Note: Always pick triangles first, then vertices.
    The former renders vertices dirty.

- Region
  - Make triangles / vertices accessible

  - Add 'validateIndices()' to add indices for triangles,
    code moved from the GLRegion* impl.
    Shall be refined later!

- GLRegion
  - Passing 'RegionRenderer' instead of RenderState ..
    reducing argument numbers and aligning all related
    'render' methods while giving association to the RegionRenderer.

- Renderer -> RegionRenderer,
  dropping 'intermediate' RegionRenderer

  - Dropping draw() in RegionRenderer, should be issued simply
    by GLRegion in a unique fashion.

- Dropping RegionFactory
  Too simple code as-is, simply invoke in Region.create(..)

- Overall:
  - Add 'final' qualifier

  - Remove overloaded methods
    where rither default args can be used
    or a followup method call completes the 'intention'.
