[Geotiff] cropping of a GeoTiff

[John Mitchell]

Hi Matt,

Thanks for the suggestions.  I tried your suggestion below:
Cropping can be done interactively with OpenEV, see

> /Main/ClipRasterWithoutArcInfo for an example.


I followed all your steps and it ran the translation but when I opened up
the translated file it still is the entire image not the cropped image that
I outlined.
