Chun-wei Fan 46a8a3fe31 gdk[cairo|gl]context-win32.c: Use gdk_win32_surface_handle_queued_move_resize() 
Use the shared function that was added in the previous commit, to simplify
things.

Also make gdk_win32_surface_get_queued_window_rect() and
gdk_win32_surface_apply_queued_move_resize() back into static functions, since
they are now used only by the code in gdksurface-win32.c
