At the moment the only plugin that can shave off background pixels and make
them transparent is the mosaic one.
So in order to get where you want you should do a mosaic of just one tile.
The background color handling is actually generic and could be moved up into
the base reader classes so that it
can be used for all formats... it's something we'd like to do anyways, but
not a quick change.
