Hidden line removal progress

Also I was thinking for the background bitmap image to maybe shrink that down by half in width and height to get a downsampled antialiased result with a bit of blending in the border areas and also cutting down file size by a ways.

Do you guys think that would be good or is it better to just keep a finer grained but non-antialiased bitmap in there?
