DummyGLContext will now attempt to load OpenGL and OpenGL ES entry
points when a suitable OpenGL context is current on the calling thread.
This allows OpenTK to be used on contexts created through third-party
toolkits.
Added GraphicsContext() constructor that takes an existing, valid OpenGL context. This can be used for interop with third-party toolkits which create the OpenGL context themselves.
Removed OpenTK.Platform.Utilities.CreateWindowInfo and made the platform-specific CreateWindowInfo methods public (e.g. CreateX11WindowInfo).
Moved Mono Windows.Forms-specific code into X11GLControl.
Removed OpenTK.Platform.Utilities.IsIdle.
Removed obsolete methods from OpenTK.Platform.Utilities.
Marked OpenTK.Platform.Utilities.CreateGraphicsContext as obsolete (use GraphicsContext constructor instead).
Made IWindowInfo implementations private.

* 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.
Removed OpenTK.Graphics.Glu class (reason: deprecated upstream; most functionality provided by OpenTK math; not compatible with OpenGL 3.0+.) OpenTK.Graphics.Glu can be accessed through OpenTK.Compatibility.
Added OpenGL|ES-specific ErrorHelper classes.
Moved OpenTK.Graphics.DisplayDevice and OpenTK.Graphics.DisplayResolution to the root OpenTK namespace (reason: their functionality is not specific and does not depend on OpenTK.Graphics).
Split Graphics*Exception classes into different files.
Made GraphicsErrorException public (reason: necessary for OpenTK.Compatibility).
Do not query actual GraphicsMode.Default in DummyGLContext constructor. Doing so creates a temporary context, which should not be done when creating a dummy context.
Fixed issue [#993]: "Possible bug in GraphicsContext.CreateDummyContext()".
Improved CreateDummyContext logic to detect and use the context handle of the current thread or a specified handle.
Removed GetCurrentContext() methods from platform-specific context implementations (everything now goes through the relevant IPlatformFactories).
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.
