+*
+*   raylib 1.5.0 (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 (including AngelCode fonts and TTF)
+*     Multiple textures support, including compressed formats 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
+*     GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP)
+*     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
+*     stb_truetype (Sean Barret) for ttf fonts 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 (struct Color is 4 byte)
+*     One custom default font is loaded automatically when InitWindow()
+*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
+*     If using OpenGL 3.3 or ES2, two default shaders are loaded automatically (internally defined)

+*     Hardware accelerated with OpenGL (1.1, 3.3 or ES2)
+*     Unique OpenGL abstraction layer [rlgl]
+*     Powerful fonts module with SpriteFonts support (including AngelCode fonts and TTF)
+*     Multiple textures support, including compressed formats 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:

+*
+*   raylib 1.5.0 (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 (including AngelCode fonts and TTF)
+*     Multiple textures support, including compressed formats 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
+*     GLAD for OpenGL extensions loading (3.3 Core profile, only PLATFORM_DESKTOP)
+*     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
+*     stb_truetype (Sean Barret) for ttf fonts 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 (struct Color is 4 byte)
+*     One custom default font is loaded automatically when InitWindow()
+*     If using OpenGL 3.3 or ES2, several vertex buffers (VAO/VBO) are created to manage lines-triangles-quads
+*     If using OpenGL 3.3 or ES2, two default shaders are loaded automatically (internally defined)
