GHOST: Add new interface to manage offscreen contexts.
Offscreen contexts are not attached to a window and can only be used for rendering to frambuffer objects.

GLX implementation : Clément Foucault (fclem)
WGL implementation : Germano Cavalcante (mano-wii)
Other implementation are just place holder for now.
