Trying to find the best way to integrate Oculus support into raylib,
making it easy for the user...

Not functional yet...

Internal modelview and projection matrices can be replaced before
drawing.

To avoid additional dependencies

Moved AudioError enum inside audio.c

mod player

The only thing I did not change was the _g for globals. Is there any
other way we can mark globals?

This is a first step toward a bigger project. Some modules could be
ported to header-only to be used as standalone.

Checking some files to be converted to header-only

Still working on the sample but almost finished. Some rlgl internals
redesign required and it will be ready!

Tint color could be applied to colDiffuse... but what's the best way?
Replace it? Multiply by? A point to think about...

Functions renamed to improve library consistency

Useful to save small data files (configuration and so)
For bigger files, external data storage should be used (SDCard)

Standard Lighting (3/3)

- Added normal and specular maps to standard shader.
- Added full tint attribute to standard shader and material data type.
- Changed point light attenuation to radius.

It tints all fragments, ignores lighting. Useful for some features like
feedback (damage color, ...).

Scaling normal depth (y axis) makes disappear the specular of
fragments... So I think it can be removed, it is not a very
useful/important attribute.

...shader and updated example.

Draw3DCircle is useful to draw point lights radius.
