…essing with the depth buffer by hand
To my eyes, it fixes #26, at least I don't see it in all the usual places. This, unlike other things I've tried, does the job without distorting the rendering of ramps and other 'thin' objects that don't really need adjustment. That could also be due to the improvement on how the 'thin' objects are detected, I wasn't waiting until after the geometry had been put into its final scale. glPolygonOffset worked suspiciously well to fix this with whatever values I tried in it
