...to avoid issue on Arch Linux

Fix typo in raymath.h

Usefult to draw rectangles using default font texture

Not usable any more, raylib changed internally

Make physac work on OS X

Physac wasn't working on OS X.  It looks like the necessary timing code wasn't being compiled in by the preprocessor.

fixes #340

To multiply Vector3 by Vector3

Moved to own repo at @raysan5/raylib.com

For consistency!

Now it works great with reviewed maths

Some other tweaks...

Update Makefile in `examples/`

We need to grab the OS name before determining what the path should be.

Now it should be coherent with OpenGL math standards

Exposed some raymath useful functions to raylib API

Consistent with similar functions in raymath

Still shader dependant, locations set should be moved out

SetMaterialTexture() and UnsetMaterialTexture()... too shader
dependant...

Corrected compilation for OpenGL 1.1
Review mesh data uploading to GPU

Moved PBR material loading to example, right decision?

Able to make a .dylib for OS X
