OpenSCAD Bitmap Fonts Module

I made a quick feasibility study for 16bit Dings. We probably need about 32 bits to make it smooth, but is there a simple icon editor that could save into 1\'s and 0\'s ? (I just used emacs picture mode, but it\'s a bit of a pain to work with 1\'s and 0\'s...)

I also added an overlap parameter so that OpenScad doesn\'t complain if 2 cubes just share a single edge. Overlap can be really small. You may pick up this idea and integrate it with the original code in some way :)

OpenScad code may need to be improved. It\'s working, but again, it\'s just a test...
