[GEMPAK #CCZ-968878]: NMAP2 CONUS view issue in 5.10.1 release

Brian,

There is a bug in the 5.10.1 image translation matrix for the X pixmap (The 
first column
has an offset applied when the GAREA is being set other than dset).

I have the fix for the driver library, as it is in the 5.10.2 distribution. Did 
you build 
from source, or use a compiled binary? I'll have to repost the binary 
distributions once I 
have them rebuilt. Or, I can send you the source changes if you built yourself.
