Code

Make toolpath cameo-friendly and use cameo for tool size compensation.

Browse Source 
- cntr/cam/doit: use cameo
- cntr/cam/pcb.pl (cut): use exact value of pi, to make sure arcs meet
  with lines connecting to them
- cntr/cam/pcb.pl (hhole): force cut to be continuous
- cntr/cam/pcb.pl (arc, hhole, pcb): don't compensate for the tool size.
  Cameo now does this for us.
- cntr/cam/pcb.pl: switch to 2nd piece position
