Summary: Memory bitmap routines fail on pre-locked bitmaps

Initial Comment:
All of the current memory routines fail to work if the destination or the source bitmap is already locked. The intended behaviour should be for them to be able to use pre-locked bitmaps, if possible, to minimize the number of locks required. E.g. the user might lock a specified region of the screen, and perform multiple memory blits to it without any intermediate locks/unlocks. As is, this is impossible with the current behaviour.
