What happens if the user value implies fully or partially out-of-canvas rendering? For the former case, we may want to print a warning and reposition the window. If a partial window is drawable, then negative values can be valid and the lower range bound should be INT_MIN Also, the user can't position a window at top-left (0,0), so the default should probably be INT_MAX.
