    winsys-glx: map X window automatically if not foreign
    
    For now we are going for the semantics that when a CoglOnscreen is first
    allocated then it will automatically be mapped. This is for convenience
    and if you don't want that behaviour then it is possible to instead
    create an Onscreen from a foreign X window and in that case it wont be
    mapped automatically.
    
    This approach means that Cogl doesn't need onscreen_map/unmap functions
    but it's possible we'll decide later that we can't avoid adding such
    functions and we'll have to change these semantics.
