RGSS allows the source rectangle in both `blt` and `stretch_blt` to lie outside the source bitmap bounds (treating the missing data as (0, 0, 0, 0)) and to be inverted (in which case the blitted image is also inverted). This commit only hanldes a corner case that arises in the game "Last Scenario"; emulating the full RGSS behavior is however desirable.
