Opentk/Source/OpenTK/Platform/X11/X11Keyboard.cs
the_fiddler c47893dae6 Corrected critical bug in X11/API.cs: VisualInfo.visualid was int where it should have been IntPtr, causing incorrect visuals to be created on 64bit platforms.
Removed the OnCreate/OnDestroy methods from INativeGLWindow.
Added convenience overloads to OpenTK.OpenGL.GL: Color3 and Color4 can now take a System.Drawing.Color directly.
