[Werner Almesberger <werner@...>]

I have a Gerber file of a board outline with arcs that I need to export
to pcbnew. gerbview doesn't support arcs yet, so I gave implementing it
a try. The patch is below. Here's the example I used:

From
http://downloads.openmoko.org/developer/schematics/GTA02/gta02_outline_footprints_netlist.tar.bz2
the file
gta02_outline_footprints_netlist/gen020.pho

And this is the resulting board (shifted, rotated, and flipped):
http://svn.openmoko.org/trunk/gta02-core/gta02-core.brd

Add support for exporting arcs in non-copper layers to gerbview.
