It has to do with graphics support, because tex and pdftex support
different graphics formats. Since we don't currently have any graphics,
it's dead code. I think you can actually do away with it anyway because
TeX should support graphics file references without extensions, ISTR.
So the actual reason for this might have been RTF support.
If it's in the way, remove it. We can always add it back when someone
wants to add a graphic. (And in that case we'll probably have to do
some additional coding somewhere anyway.)
