Well, if using cairo_show_glyphs() was as easy as this, show_text()
would have been doing it...

The short answer lies in FcFreeTypeCharIndex() or FT_Get_Char_Index().
That's what show_text() already does.

The long answer is 25 thousand lines longer.  And that's why you should
use pangocairo.

PS.  Keith, David, should the toy text backend switch to
FcFreeTypeCharIndex()?  What are the benefits?  We sure don't cache the
result....  Who cares though.
