window: Allow _gtk_window_set_allocation to return a modified allocation
Update the documentation and users of this function to handle the future case that that we have some internal decorations to the window and useable allocation is thus smaller. By having a separate out parameter there is no need to have an in/out function and allows for greater robustness. The current implementation simply returns the allocation provided.
