- Added subdivided meshes with more triangles. For some weird reason those can achieve better performance, especially the #5 one. Still use the regular one by default for now.
- Cleaned up some c-style casts.
- Cleaned up some NULL comparisons.
- Cleaned up some unused functions.
- Cleaned up UpdateTexture function and combined a few others.
