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

Now GLFW3 windows/context creation works ok and a sample red rectangle
has been drawn using rlgl. Next step is working in tracking
position/orientation maths and try to get a simple 3d scene...

Now it's possible to render to texture, old postprocessing system will
be removed on next raylib version.

Redesigned to work as standalone and support fordward-compatible context
(shaders review)

Depth test disabled for 2D and only used on 3D; consequently LINES vs
TRIANGLES vs QUADS buffers drawing order maters... but blending also
works ok.

Requires Shader access functions review

sin(), cos() functions cached and replaced by float c99 versions sinf(),
cos()

Added support for single header implementation and also inline functions
support

Reviewed vertex type variables

- New model and view transformation matrix added, useful for shaders.
Modelview matrix not deleted to keep opengl 1.1 pipeline compatibility.

- New extra function added DrawModelWiresEx() to set a rotation and
scale transformations to a wire model drawing.

- Other writing and little audio.c bug fixed.

Updated functions:
Image GetTextureData(Texture2D texture);
void *rlglReadTexturePixels(Texture2D texture);

LoadTextureEx() - Simplified parameters
UpdateTexture() - Added, allows updating GPU texture data

- Renamed function rlEnableFBO() -> rlEnablePostproFBO()
- Defined struct FBO
- Moved FBO creation to function: rlglLoadFBO()
- Reviewed rlglReadTexturePixels(), trying to support OpenGL ES -IN
PROGRESS-

Useful to enable additive blend mode for particles

Requires raymath as standalone and GLEW

Shader functionality owns to rlgl, not core module

- Camera system moved to a separate module [camera.c]
- WIP: Added customization functions for camera controls
- Added custom shaders support on batch drawing
- Complete redesign of textures module to support multiple texture
formats (compressed and uncompressed)

Moved functions: LoadShader(), UnloadShader()
Add support for PVR textures compressed/uncompressed
WIP: Detect available extensions for compressed textures

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

Corrected GetMouseWheelMove()
Corrected camera system
Reviewed cubicmap resolution (collision detection)
Added QuaternionTransform()
WIP: Raycast system (not working)
WIP: Reviewing axis-angle rotations...

Shader system has been completely redesigned
Added support for multiple texture color modes

Custom shaders for models
Postprocessig on FBO (in progress)
Some useless spaces removed

Corrected some bugs on the way...
Automatically convert textures to POT on RPI and WEB

Added PLATFORM_WEB support (emscripten-webgl)
[audio] Added LoadSoundFromWave()
[textures] Added LoadTextureFromImage() to replace CreateTexture()
Some TraceLogs edited...

View CHANGELOG for description on small fixes and add-ons

This is a huge update. Check CHANGELOG for details

No-parameters functions use the prototype style FunctionName(void);

Set default raylib to use OpenGL 1.1 (compatibility issues on ATI cards)

Check CHANGELOG for a detailed list of changes

View CHANGELOG for a detailed list of changes

Added a Tracing/Log system
Added OGG stream music support (DOESN'T WORK)
Added Compressed textures support
* This update is probably very buggy...

Nearly a complete rework of Models module
Some teaks on multiple functions
