The Open Toolkit is set of fast, low-level C# bindings for OpenGL, OpenGL ES, OpenAL and OpenCL. It runs on all major platforms and powers hundreds of apps, games and scientific research. It provides bindings for GLFW windowing, input and a game loop, and is the perfect start for your own game engine. OpenTK comes with simple and easy to follow tutorials for learning *modern* OpenGL. These are written by the community and represent all of the best practices to get you started.

FIX: Made it so that the singular check in `Matrix4.Invert` is the same between platforms.
In particular this fixes an issue where the singular check was too aggressive in the SSE3 path. (@NogginBops)
FIX: Made checking for OpenAL extensions not crash if the extension wasn't present. (@NogginBops)
FIX: Fix to the rewriter to not generate invalid IL on some GLES functions. (@NogginBops)
Updated to not contain broken links. (@asears)
