lua_bitmap_composite: Don't OOB with outside if no right gap
If lua_bitmap_composite encountered a cut, it warped to the right
edge of the gap and then proceeded to composite a pixel. This is
incorrect, because the right edge can be beyond draw area, resulting
OOB access. Fix this by checking that the warped right edge is in
draw area, and if not, moving to next row.
