Yes (although I have .ttf files which are non-scalable as well).

Ok. Perhaps I didn't understand the code well enough then. It looked to
me like any bitmap font needed to go through the slower path. Your test
was exact (for TTF fonts), using the faster path precisely when the
outlines were used. My test is less precise, it uses the faster path
only when the font couldn't possibly have bitmaps.
I believe that the result will be that my test executes the slower path
for all fonts which have bitmaps while your test executes the slower path
only when actually using said bitmaps.

I think your test is not for the existence of embedded bitmaps, but whether
those bitmaps are actually in use. My test detects the presence of any
I believe that my test will generate the right results, but it will be
slower in the case where a font has embedded bitmaps that aren't used.
