Plus bonus graphical artefacts around the edges of such! In the end the majority of this code was rather easy: take the upwards floor drawing code and reflect it. However, there were many edge-cases and plenty of off-by-one pixels and rounding issues that didn't quite work the same way going down as they do going up. Also the object drawing code used to take advantage of the fact that the z-buffer was painted bottom-up only, so that required change too.
