Hi,

I just revisited the --bg-image background image feature to create a
footprint for a gps module.

I see a snag in the behaviour:
It seems as if the gtk version of pcb skews each line in the image with a
pixel or two for each line. This results in a diagonal wrap in the image

I have tested pcb-gtk versions 20110918-7 and 20140316-3 in Debian, and
both show the same
skew.

I also tested gtk-lesstif 20140316-3 and 20110918-7 and here the image is
wrapped evenly
about 1/10th into the picture. This creates a vertical wrap.

I have tried both jpg and ppm with the gtk version and ppm with the lesstif
version

I tried to compile pcb from latest git source, but currently I have some
issues making it crash on me,
so I can't tell how the background picture will look there.

I would be happy if anybody with a bit of extra time could try to use a ppm
or a jpg as background.
I think any reasonably sized picture can be used for test.

I would also be happy if somebody could give me the git hash of a
reasonably new commit known to work so I can clean up my build directory
and build the sources from that hash.
