* Source/OpenTK/Platform/Windows/WinGLContext.cs:
* Source/OpenTK/Platform/Dummy/DummyGLContext.cs: Added IsDisposed
property to IGraphicsContext and implemented in all context classes.
Removed 'bool disposed' fields from these classes in favor of the
new property.
Added GraphicsContextBase, which acts as the foundation of all IGraphicsContext implementations.
Added DesktopGraphicsContext, which acts as the foundation of all desktop (i.e. not ES) IGraphicsContext implementations.
Modified all IGraphicsContext implementations to inherit from GraphicsContextBase and/or DesktopGraphicsContext.
Added GraphicsContext.ErrorChecking property to temporarily disable error checking if necessary.
Error checking is now added to all functions in debug mode (the generator would miss specific CLS-compliant overloads before).
Added OpenGL 3.0 support for GLX contexts.
Added support for creating dummy contexts (useful if you are creating contexts from an external library).
Cleaned up unused and stale code.
Update X11 stack to use System.Windows.Forms.XPlatUI for its Display, Screen and RootWindow.
Fixed mode setting for X11GLControl.
Fixed X11 shutdown (was generating X11 errors).
Added DeviceContext getter to WinWindowInfo.
Made IWindowInfo disposable.
Added documentation to many public methods.
Worked around a Mono 1.2.4 bug with Handle creation on Windows.Forms.Control.
Updated GL.BuildExtensionList to correctly parse GL_VERSION when in indirect rendering mode.
Fixed crash errors in X11GLContext.CreateContext and X11GraphicsMode.
Added a ref overload to Glx.ChooseVisual()
IGraphicsContext.MakeCurrent now takes an IWindowInfo parameter. This allows the user to change to window is context is bound to (untested).
Renamed XyzWindowInfo.Handle to XyzWindowInfo.WindowHandle.
Fixed vsync on X11.
Updated GraphicsContext interface, for better extensibility. Some public functions were moved to IGraphicsContextInternal.
Renamed DisplayDevice.PrimaryDisplay to DisplayDevice.Default.
Updated and documented new GameWindow constructors.
Improved GameWindow.Exit, added GameWindow.ExitAsync() and improved error handling.
Improved GraphicsContext and NativeGLWindow APIs (construction in constructor).
Made ContextHandle public.
Updated to use GraphicsFormat instead of DisplayMode.
Updated to use ColorDepth instead of ColorMode.
Improved GameWindow Exit handling, and handling of failed context creation.
Improved WinGLContext creation code, to allow for FSAA support in the future.
Fixed several shutdown bugs in WinGLContext and GraphicsContext.
Context creation no longer relies on IGLContextCreationHack.
X11GLContext is not working at the moment.
