* raylib is SIMPLE and EASY-TO-USE, I tried to keep it compact with a small set of functions, if a function is too complex or
has not a clear usefulness, better not to include it.

lots of parts of the library have been reviewed, lots of bugs have been solved and some interesting features have been added.
First big addition is a set of [Image manipulation functions](https://github.com/raysan5/raylib/blob/develop/src/raylib.h#L673) have been added to crop, resize, colorize, flip, dither and even draw image-to-image or text-to-image. Now a basic image processing can be done before converting the image to texture for usage.

Now a basic image processing can be done before converting the image to texture for usage.
SpriteFonts system has been improved, adding support for AngelCode fonts (.fnt) and TrueType Fonts (using [stb_truetype](https://github.com/nothings/stb/blob/master/stb_truetype.h) helper library). Now raylib can read standard .fnt font data and also generate at loading a SpriteFont from a TTF file.

New [physac](https://github.com/raysan5/raylib/blob/develop/src/physac.h) physics module for basic 2D physics support. Still in development but already functional. Module comes with some usage examples for basic jump and level interaction and also force-based physic movements.

[raymath](https://github.com/raysan5/raylib/blob/develop/src/raymath.h) module has been reviewed; some bugs have been solved and the module has been converted to a header-only file for easier portability, optionally, functions can also be used as inline.
[gestures](https://github.com/raysan5/raylib/blob/develop/src/gestures.c) module has redesigned and simplified, now it can process touch events from any source, including mouse. This way, gestures system can be used on any platform providing an unified way to work with inputs and allowing the user to create multiplatform games with only one source code.

Other important improvements are the functional raycast system for 3D picking, including some ray collision-detection functions, and the addition of two simple functions for persistent data storage. Now raylib user can save and load game data in a file (only some platforms supported). A simple [easings](https://github.com/raysan5/raylib/blob/develop/src/easings.h) module has also been added for values animation.

notes on raylib 1.5
-------------------
On July 2016, after 5 months of raylib 1.4 release, arrives raylib 1.5. Probably this new version is the biggest boost of the library ever, lots of parts of the library have been redesigned, lots of bugs have been solved and some **AMAZING** new features have been added.
VR support: **Oculus Rift CV1**. raylib supports Oculus Rift CV1, one of the most anticipated VR devices in the market. Additionally, raylib supports simulated VR stereo rendering, independent of the VR device; it means, raylib can generate stereo renders with custom head-mounted-display device parameteres, that way, any VR device in the market can be **simulated in any platform** just configuring device parameters (and consequently, lens distortion). To enable VR is [extremely easy](https://github.com/raysan5/raylib/blob/develop/examples/core_oculus_rift.c).
New materials system: now raylib supports standard material properties for 3D models, including diffuse-ambient-specular colors and diffuse-normal-specular textures. Just assign values to standard material and everything is processed internally.
New lighting system: added support for up to 8 configurable lights, supported light types are **point light**, **directional light** and **spot light**. Just create a light, configure it and raylib manages render internally for every 3d object using standard material.
Complete gamepad support on Raspberry Pi: Gamepad system has been completely redesigned. Now multiple gamepads can be easily used and configured and gamepad data is read and processed in raw mode in a second thread.
Redesigned physics module: physac module has been converted to header only and usage has been simplified. Performance has also been singnificantly improved, now physic objects now are managed internally in a second thread.
Audio chiptunese support and mixing channels: Added support for module audio music (.xm, .mod) loading and playing. Multiple mixing channels are now also supported. All this features thanks to @kd7tck amazing work.
This new version is so massie that is difficult to list all the improvements, most of raylib modules have been reviewed and [rlgl](https://github.com/raysan5/raylib/blob/develop/src/rlgl.c) module has been completely redesigned to accomodate to new material and lighting systems. You can check [CHANGELOG](https://github.com/raysan5/raylib/blob/develop/CHANGELOG) file for a more detailed list of changes.
Up to 8 new code examples have been added to show the new raylib features and also some samples to show the usage of [rlgl]() and [audio]() raylib modules as standalone libraries.
Lots of code changes (more than 300 commits) and lots of hours of hard work have concluded in this amazing new raylib 1.5.

/**********************************************************************************************
*
* 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)

* 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)

/**********************************************************************************************
*
* 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)

/**********************************************************************************************
*
* [physac] raylib physics module - Basic functions to apply physics to 2D objects
* physac 1.0 - 2D Physics library for raylib (https://github.com/raysan5/raylib)
*
* Copyright (c) 2016 Victor Fisac and Ramon Santamaria
* // TODO: Description...
*
* CONFIGURATION:
*
* #define PHYSAC_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define PHYSAC_STATIC (defined by default)
* The generated implementation will stay private inside implementation file and all
* internal symbols and functions will only be visible inside that file.
*
* #define PHYSAC_NO_THREADS
* The generated implementation won't include pthread library and user must create a secondary thread to call PhysicsThread().
* It is so important that the thread where PhysicsThread() is called must not have v-sync or any other CPU limitation.
*
* #define PHYSAC_STANDALONE
* Avoid raylib.h header inclusion in this file. Data types defined on raylib are defined
* internally in the library and input management and drawing functions must be provided by
* the user (check library implementation for further details).
*
* #define PHYSAC_MALLOC()
* #define PHYSAC_FREE()
* You can define your own malloc/free implementation replacing stdlib.h malloc()/free() functions.
* Otherwise it will include stdlib.h and use the C standard library malloc()/free() function.
*
* LIMITATIONS:
*
* - There is a limit of 256 physic objects.
* - Physics behaviour can be unexpected using bounciness or friction values out of 0.0f - 1.0f range.
* - The module is limited to 2D axis oriented physics.
* - Physics colliders must be rectangle or circle shapes (there is not a custom polygon collider type).
*
* VERSIONS:
*
* 1.0 (14-Jun-2016) New module defines and fixed some delta time calculation bugs.
* 0.9 (09-Jun-2016) Module names review and converted to header-only.
* 0.8 (23-Mar-2016) Complete module redesign, steps-based for better physics resolution.
* 0.3 (13-Feb-2016) Reviewed to add PhysicObjects pool.
* 0.2 (03-Jan-2016) Improved physics calculations.
* 0.1 (30-Dec-2015) Initial release.
