It seems that drawRectangle() was calling gdImageFilledRectangle() with ymax values less than ymin and so nothing was being drawn. I assume this only affects the GD rendering. I am not sure when the issue was introduced. Presumably it worked once upon a time.
Fix by flipping y's as needed in drawRectangle() in trunk (r10288).
It seems reasonable to port this fix back to the stable branch, but there has so far been no user complaints, so I'll defer that till there is a need.
