Thinking about Herbert and Rob's list of loadable graphics formats, I 
discover the following code:

string const findTargetFormat(string const & from)
{
        typedef GImage::FormatList FormatList;
        FormatList const & formats = GImage::loadableFormats();

Now GImage::loadableFormats() returns a FormatList, not a FormatList &, so 
why does this not die horribly?
