OpenTK will now use the same GLXFBConfig to create the INativeWindow
and IGraphicsContext on Linux/X11. This resolves an issue where OpenGL
3.x contexts could not be created on some graphics drivers (e.g.
nvidia binary.)
You cannot create an X11/OpenGL context without the GLX extension.
OpenTK will now throw a `NotSupportedException` when this condition is
encountered.
In some cases, it may be possible to enable the EGL backend by passing
`GraphicsContextFlags.Embedded` to the `GraphicsContext` constructor.
EGL and NSOpenGL do not offer an EXT_swap_control_tear equivalent so
use regular vsync for now. The relevant extension string is now
correctly checked on WGL and GLX.
GLX can return valid function pointer to unsupported functions.
We need to check for extension support in addition to the
function pointer.
Fixes crash on OpenSUSE 13.1 in VirtualBox.
It is now possible to pass a non-realized GraphicsMode to the X11GLContext and X11GLNative constructors. A non-realized GraphicsMode is a GraphicsMode with a null Index (i.e. which has not passed through SelectGraphicsMode()).
glXGetProcAddress may return a non-null value even if a function is not
supported by the server. We need to check the extension string using
any GLX extensions. Fixes issue http://www.opentk.com/node/3111 "GLX
extension support is not checked correctly".
Furthermore, mode selection is now performed explicitly by the
X11GLContext constructor.
GLX entry points are not bound to a specific context. This means that, unlike WGL, GLX does not require a temporary context in order to load its entry points!
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.

* Platform/X11/X11GLContext.cs: Modified BindingsBase to define
abstract GetAddress method (reason: removes OpenTK.Graphics-specific
code from BindingsBase and allows it to be used in different
bindings).
Implemented GraphicsBindingsBase and modified the OpenGL and OpenGL|ES
bindings to use this.
Modified the GLX bindings to inherit from BindingsBase (reason:
reduces code duplication for extension loading).

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).
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.
Added xml documentation for the ContextHandle.
Made the casts between ContextHandles and IntPtrs explicit.
Updated all ContextHandle consumers to reflect the explicit cast.
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.
