[Xastir] online terraserver maps black, too

[Dick Repasky]

I wrote earlier about having trouble with .geo files from splat. I
decided to try some of the .geo files that are distributed with xastir.

All the terraserver .geo files render as sheets of solid black. Online
TIGER maps are fine as are WMSRadar.geo, TXRadar.geo and USRadar.geo.

Do you think that this might have to do with compiling against
graphicsmagick rather than imagemagick?
