Hello all:

As part of the on-going work to consume less memory in our
application, are starting to use the osgsquish library to create DXT
images from our existing PNG images.  The issue we are running into is
that we don't want to have to reprocess these image each time we load
them from cache.  Instead we would like to download them once, convert
them to DXT once, and then store them to cache for future use.

The question is, how can we store and OSG::Image (in DXT pixel format)
in a binary form to disk that will read/write as fast as possible.  I
was thinking of something like .osb, but it doesn't support individual
FCs.  Then I thought of looking for a binary image file format, but I
don't see anything like that.  Is there some other option that I am
missing?

-Allen
