I am trying to store images (GIF, JPG etc) in ".osga" archive files. This
works for image types whose plugin implements a writeImage() method, but for
those that don't, there is no pathway by which to get the image into the
archive. This is straightforward to demonstrate:

  osgarchive --archive test.osga --insert image.gif
  osgarchive --archive test.osga --list

The GIF file will not be present in the listing.

I'd like to get peoples' thoughts on the best way to handle this (short of
implementing writers for every plugin).

One idea would be: if no writer is available, fall back to simply doing a
straight byte-copy of the image's source file (if available) into the
archive.

I am happy to contribute the implementation once we can agree on one.
Thanks!
Glenn
