Support multiple texture formats (uncompressed and compressed)
Postprocessing shaders support
Model struct redefined and improved
Extended loading functions for Textures and Models
Simplified functions: DrawPlane(), DrawQuad()
Deleted functions: DrawPlaneEx(), DrawGizmoEx()
Now Text module only depends on Textures module
Shapes: Reviewed functions to low lines/triangles usage
Removed useless tabs and spaces around code
We have three vertex buffers: lines, triangles and quads for textures.
Drawing in a desired order could become a nighmare... noww it seems it
works prety well...
