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.
