But every image goes through our hands. We can just rescale this under certain 
conditions. At least the uncompressed textures are unproblematic.
I would introduce some property that is evaluated in the image load callback 
than. Today the chain of readerwriter options should in any case provide a 
simgear options object that contains the property tree that could be queried 
then.
