Subject: Graph: GLSL fix, Adding renderModes bits instead of dedicated
 booleans, Region/GLRegion, ..

GLSL fix:
  - allowing #version tag
  - add uniform textureSize (ES2)
  - fix int/float conversion

Region/GLRegion:
  - non OpenGL Region and GL related GLRegion split

Region/Renderer renderModes bits (def. in Region)
  - user creates a Renderer* impl .. and derive Region*'s from outline,
    possibly from a different code path.

  - to avoid mode explosion, a bit field is being used for now

- Renderer: remove flushCache(), since non caching impl. is intended,
            or caching by an external user transparent object.
