I've just noticed the comment in gtkfont.c that said wouldn't it be
nice to find a way to avoid the GDK pixmap-stretching code when using
Pango fonts. We now do support this, but we support it in gtkwin.c
rather than gtkfont.c - because we do it using a Cairo transformation
matrix, so it still takes place at the level above Pango rather than
in Pango proper. (I never did find out whether Pango itself included
facilities to arbitrarily stretch a font.)
Hence, this comment is useless now. Discard.
