[Jon Evans <jon@xxxxxxxxxxxxx>]

Hi all,

I want to bump this thread and ask developers who use GerbView a lot to
take a look at my branch again.
Most things are working now, so I'm almost ready to submit it as patches so
that more people can play with it and/or work on it.

Things that definitely don't work yet:
- Negative images (in either canvas)
- Negative items aren't transparent in Cairo canvas - I may need to
implement some kind of image compositing mode in Cairo to fix this.
- OpenGL caching has to be disabled otherwise settings changes take a long
time to update; not sure why yet.
- Selected items disappear unless you are zoomed out (see my other thread
asking about this issue)

git@xxxxxxxxxx:craftyjon/kicad.git branch gerbview_gal

Please let me know if you find bugs, files that don't look like they
should, or have suggestions!

Best,
Jon
