I don't know if I got it right - the result doesn't look that great to me -
but at least the infrastructure is there.
This, I think, marks the point where BS2 graphics is pretty much done. Some
functions haven't been unstubbed yet, but I believe they're used for
debugging and/or profiling. I'm not sure they're worth the trouble.
Of course, there is still testing and clean-ups to make. For instance, I'd
like DrawSprite() to use malloc() a bit less.

sprites are drawn, but I think that's how it should be.
1: No bells or whistles.
2: This setting adds sprite blending, e.g. the smoke at the docks or the
display cases at the Glease Gallery.
3: This setting adds light map support, e.g. when walking under the shack
at the docks.
4: This setting adds better scaling algorithms.
The first three settings should work fine now. In fact, the third setting
is what we used to implement. The fourth setting still needs work and
testing. I've added code for downscaling case, but frankly I'm not
convinced the result is any better than with the simpler scaler. I usually
can't even tell the difference.
Of course, my translation of the original code could very well be buggy.

unnecessary stuff from our own Surface class. The former allows the in-game
dialogs to at least sort of work, and the latter gained me a few frames per
second, according to the built-in FPS counter.
