OpenGL Renderer: Do some minor tune-ups.

- Remove some methods in OpenGLRenderer_2_0 and OpenGLRenderer_2_1 that have negligible contribution to either performance or code simplicity.
- OpenGLRenderer_1_2, OpenGLRenderer_2_0, and OpenGLRenderer_2_1 are now instantiated with their specific variant IDs.
- Calls to malloc_alignedCacheLine() have been replaced with the more appropriate malloc_alignedPage().
- Do some misc. code cleanup.
