raylib/src/raylib.h
victorfisac 1793f2c3b8 Added collision check between ray and box 
- Added CheckCollisionRayBox() function.
- Updated and improved core 3d picking example (currently working as
expected).

*
* raylib 1.4.0 (www.raylib.com)
*
* A simple and easy-to-use library to learn videogames programming
*
* Features:
* Library written in plain C code (C99)
* Uses C# PascalCase/camelCase notation
* Hardware accelerated with OpenGL (1.1, 3.3+ or ES2)
* Unique OpenGL abstraction layer [rlgl]
* Powerful fonts module with SpriteFonts support
* Multiple textures support, including DDS and mipmaps generation
* Basic 3d support for Shapes, Models, Heightmaps and Billboards
* Powerful math module for Vector and Matrix operations [raymath]
* Audio loading and playing with streaming support (WAV and OGG)
* Multiplatform support, including Android devices, Raspberry Pi and HTML5
*
* Used external libs:
* GLFW3 (www.glfw.org) for window/context management and input
* GLEW for OpenGL extensions loading (3.3+ and ES2)
* stb_image (Sean Barret) for images loading (JPEG, PNG, BMP, TGA, PSD, GIF, HDR, PIC)
* stb_image_write (Sean Barret) for image writting (PNG)
* stb_vorbis (Sean Barret) for ogg audio loading
* OpenAL Soft for audio device/context management
* tinfl for data decompression (DEFLATE algorithm)
*
* Some design decisions:
* 32bit Colors - All defined color are always RGBA
* SpriteFonts - All loaded sprite-font images are converted to RGBA and POT textures
* One custom default font is loaded automatically when InitWindow()
* If using OpenGL 3.3+ or ES2, one default shader is loaded automatically (internally defined)
