gEDA-user: PCB: Rotate in steps of 30 and 45 degree?

The problem isn't rotating the footprint, it's that nothing in pcb
expects pads to be other than orthogonal.  For example, the gerber
exporter can't plot angled lines with square corners, it would have to
draw them as filled polygons.  The autorouter doesn't know about them
either, nor does the optimizer.

The other problem is, of course, loss of precision.  You end up
off-grid when you rotate back to zero.
