Subject: Bug 802: Graph TextRenderer Performance Part-1 (incomplete, rendering
 artifacts)

Strategy Change:
  - Font.Glyph itself holds it's OutlineShape
    with it's default scaling.
    Triangulation is done only once per glyph!

  - A CharSequence produces a Region
    by translating and scaling each Glyphs's OutlineShape.
    This removes the need for re-triangulate - see above.
    See: TextRendererUtil

  - The indices of re-added Triangles are
    offset to the new vertices (FIXME, seems not be be accurate yet).

  - OutlineShape's vertices and triangles are reused if 'clean'.

  - Simplified code

  - Reduced copies

API Changes:
  - OutlineShape, Region, ...: See above

  - Removed TextRenderer, GlyphShape and GlyphString: Redundant

  - Added TextRendererUtil to produce the Region from CharSequence

Result:
  - Over 600 fps while changing text for each frame.
    Previously only ~60fps max.

TODO:
  - Region shall not hold the triangles itself,
    but the indices instead.
    This will remove the need to swizzle w/ vertices in the Region Renderer impl
    and easies reusage of OutlineShapes.
