-- t'GI.Gdk.Objects.GLContext.GLContext' is an object representing the platform-specific
-- OpenGL drawing context.
-- 
-- @/GdkGLContexts/@ are created for a t'GI.Gdk.Objects.Window.Window' using
-- 'GI.Gdk.Objects.Window.windowCreateGlContext', and the context will match
-- the t'GI.Gdk.Objects.Visual.Visual' of the window.
-- 
-- A t'GI.Gdk.Objects.GLContext.GLContext' is not tied to any particular normal framebuffer.
-- For instance, it cannot draw to the t'GI.Gdk.Objects.Window.Window' back buffer. The GDK
-- repaint system is in full control of the painting to that. Instead,
-- you can create render buffers or textures and use 'GI.Gdk.Functions.cairoDrawFromGl'
-- in the draw function of your widget to draw them. Then GDK will handle
-- the integration of your rendering with that of other widgets.
-- 
-- Support for t'GI.Gdk.Objects.GLContext.GLContext' is platform-specific, context creation
-- can fail, returning 'P.Nothing' context.
-- 
-- A t'GI.Gdk.Objects.GLContext.GLContext' has to be made \"current\" in order to start using
-- it, otherwise any OpenGL call will be ignored.
-- 
-- == Creating a new OpenGL context 
-- 
-- In order to create a new t'GI.Gdk.Objects.GLContext.GLContext' instance you need a
-- t'GI.Gdk.Objects.Window.Window', which you typically get during the realize call
-- of a widget.
-- 
-- A t'GI.Gdk.Objects.GLContext.GLContext' is not realized until either 'GI.Gdk.Objects.GLContext.gLContextMakeCurrent',
-- or until it is realized using 'GI.Gdk.Objects.GLContext.gLContextRealize'. It is possible to
-- specify details of the GL context like the OpenGL version to be used, or
-- whether the GL context should have extra state validation enabled after
-- calling 'GI.Gdk.Objects.Window.windowCreateGlContext' by calling 'GI.Gdk.Objects.GLContext.gLContextRealize'.
-- If the realization fails you have the option to change the settings of the
-- t'GI.Gdk.Objects.GLContext.GLContext' and try again.
-- 
-- == Using a GdkGLContext 
-- 
-- You will need to make the t'GI.Gdk.Objects.GLContext.GLContext' the current context
-- before issuing OpenGL calls; the system sends OpenGL commands to
-- whichever context is current. It is possible to have multiple
-- contexts, so you always need to ensure that the one which you
-- want to draw with is the current one before issuing commands:
-- 
-- 
-- === /C code/
-- >
-- >  gdk_gl_context_make_current (context);
-- 
-- 
-- You can now perform your drawing using OpenGL commands.
-- 
-- You can check which t'GI.Gdk.Objects.GLContext.GLContext' is the current one by using
-- 'GI.Gdk.Objects.GLContext.gLContextGetCurrent'; you can also unset any t'GI.Gdk.Objects.GLContext.GLContext'
-- that is currently set by calling 'GI.Gdk.Objects.GLContext.gLContextClearCurrent'.
