    gdk: Revert making get_size optional
    
    49a0ec6e95408e3484397602ad46e274cedbf98b added this hunk without
    explanations and it's obviously wrong because failing to have a get_size
    vfunc will now not set width and height and they'll end up with invalid
    values.
    
    In fact, the GdkDrawableImpl{X11,Win32,Quartz} functions do not have
    get_size implemented, so the patch was most likely an attempt to work
    around calling this function erroneously on the impl objects.
    
    The correct fix is to call impl->wrapper instead.
