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):

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