Well, I'm certainly familiar with this scenario ... I call the bottom of my
email view my event horizon.  An  email that slips below it is lost to this

Libgeotiff is only responsible for the coordinate system and georeferencing
aspect of the GeoTIFF format (it is layered on libtiff which does the actual
imaging).  The bulk of libgeotiff is about expanding coordinate systems from
the EPSG definitions, and encoding/decoding these definitions from geotiff

The hard questions with libgeotiff relate to EPSGish interpretation.
Libgeotiff is also the origin of the coordinate system dictionaries used
by GDAL, PROJ.4, PostGIS and related software.

So, briefly, since the bulk of libgeotiff activity is coordinate system
related, I felt it was a decent fit for MetaCRS.

PS. I composed message with my two children reading back parts of it,
unsynchronized with each other.  If it is a bit incoherent, consider
my circumstances. :-)
