DIG: Layering bugfix

This should fix some - maybe most - of bug #629412 ("DIG: Layer problem"). I've only gotten far enough to see the room with the buried animals, though -- I don't know about the other problems mentioned.

The problem in that room is that it's made up of five layers, but gdi._imgBufOffs[] (which despite its name is used for storing offsets into the *mask* buffer) has only four elements. In my case, the fifth one was 0, so the mask that was meant for the last layer was applied to the last one.

I'd really like to change the name of this variable, but that's beyond the scope of the patch.

Note that save/load still thinks that gdi._imgBufOffs[] is four elements, since I didn't want to break savegame compatibility. Since loadState() calls initBGBuffers() I'm not entirely convinced that the array *has* to be saved anyway.
