OpenGL Renderer: Use the fixed-point vertex list data instead of the floating-point based one, alongside other tune-ups.
- To determine polygon facing, use GFX3D's CPoly.isPolyBackFacing instead of using GLSL's gl_FrontFacing. This eases OpenGL version requirements and improves older GPU compatibility a little. - Also fix a bug where GPUs that support FBOs, but not shaders, were unable to read out their framebuffers properly.
