[Pcb2gcode-devel] Some minor fixes to pcb2gcode

[Spencer R. <sf...@me...>]

I noticed that when I was generating paths with multiple paths, the
paths on the very outside of the design were getting put right on top of
each other (see attached pic pcb2gcode_orig.png). It looks like the
bounding box being calculated wasn't taking into account the
"extra_passes" parameter.

I made a minor tweak so it looks at the tool from the "front" layer and
the extra_passes parameter and makes sure the bounding box is large
enough to contain the extra passes. See the result in the other attached
pic (openscam_board.png)

I forked the repo and made my changes in my GitHub repo here:
https://github.com/ssfrr/pcb2gcode

Does my approach seem reasonable? Is there a process for getting this
change merged into the main repository?

Thanks,
