Subject: SCI32: Activate SCI3 draw/erase list calculation algorithm

This code branch, existing since at least SQ6 but apparently never
used by any SCI2/2.1 game, is in fact the algorithm used by SCI3.

This fixes (at least) doubled rendering of transparent surfaces
like the background of the inventory window and conversation
choices panel in LSL7.
