I have created a ncgm gmeta file using a program which does a color
raster plot (using routine GCA) and then overlays it with a "flash"
(GFLAS) file of topographic/geographic lines. The plot covers the US.
I find that when I try to extract/display a local CA-NV region using
ctrans ala

ctrans -window 0.2:0.4:0.3:0.6 -viewport 0.2:0.04:0.8:0.9 -res 512x512
-d sun

I get an image which has the correct extract of the overlay but the
extract of the raster plot is incorrect (I can see that it matches up
to a region just off the NC coast). Is this a bug or a limitation of
the use of "flash" files or what?
