   It
   seems the mysterious ppcPolyGlyphBlt is calling miPolyGlyphBlt with some 0x0
   glyphs.  That is, gWidth and gHeight are 0 when it calls miPutImage.

   Is this a bug in miPolyGlyphBlt or ppcPolyGlyphBlt?

Strictly speaking it's probably a bug in miPutImage, but

   Right now, I've modified
   miPolyGlyphBlt to skip over glyphs whose height or width is zero.

That's the reasonable solution anyway.
