-*
-*   raylib 1.2 (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
-*     32bit Textures - All loaded images are converted automatically to RGBA textures
-*     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)

-*
-*   raylib 1.2 (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
-*     32bit Textures - All loaded images are converted automatically to RGBA textures
-*     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)
