Thanks to the DDS image caching code
in simgear/scene/model/ModelRegistry.cxx
(kudos Richard Harrison), we should be able to do one better and have FG
downsize
_any_ texture to a user-configurable maximum size.

This looks just it would just require tieing
SGSceneFeatures::instance()->setMaxTextureSize()
and SGSceneFeatures::instance()->getMaxTextureSize() to appropriate
properties and then letting
the resizing code in simgear/scene/model/ModelRegistry.cxx lines 428-450 do
its stuff.

Richard - any reason this wouldn't Just Work?
