[Xastir] Non-Fun with DRGs

[Brian Heaton]

All,

	I tried pulling everything put the bounding coordinate sections out of
the meta data file (cleaned up, made sure tabs were between fields,
removed trailing spaces, etc). 

	When I attempt to load the map the below debug output is produced
(debug level = 593)

	I'm open to hints and suggestions...
