[Dillo-dev] fltk font issue

A few weeks ago, bug 940 was added. A segfault. The submitter gets it with Tiny Core. I don't see it with my non-TC setup, so I asked Colin about it. He suspected that it had to do with TC's dearth of fonts. http://www.fltk.org/str.php?L2319 was added yesterday, and is about someone with dillo-2.2 getting font crashes. fltk::setfont() calling fontopen(), which gets NULL from XftFontOpen() (as the manpage says can happen). Since this is a fltk2 thing, I think this will fall to us to fix. As for whether we simply want to stick something like if (!xftfont) return; after the fontopen() call, or we want to try harder in some way, I don't know yet.
