The problem is that the way the way glyphs are/should be filled with Type 2
patterns (maybe type 1, too?) is that the glyph is not rendered, but intepreted
to a path, which is then used as a clip through which to render the pattern.

At the moment, the FAPI code only checks for a stroked font, or a charpath
operation, and is missing the fact that, in this case, we want path, even
though the original operation is a "normal" show-type operation. It creates a
bitmap and passes that to the mask rendering code - unfortantely, everything
else has been setup to accept a path, hence the crash.

Hopefully, it won't be too difficult to revise FAPI to correctly produce an
outline that can be used for clipping in these cases - I'm too tired to look
any further right now......
