Yes/No, you can't make overhangs with a HF.
But more important, this is my first real attempt at programming something 
(besides the occasional modifying a pre-recorded-office-vba-macro). The 
DF3 format is simple but for HF's TGA's or PNG's have to be manipulated, 
not up to that yet.

Sorry, I don't understand the "only two possible values ..." part.
