It seems that GTK+ spends too much time drawing the background colour in calls
to gdk_draw_layout_with_colors().  The fix is to simply do the background fill
yourself using gdk_draw_rectangle() before drawing the layout.  I filed this bug
upstream:

  http://bugzilla.gnome.org/show_bug.cgi?id=167917

The patch attached speeds up the performance tests for me, but it requires testing.

Are we incorporating this patch?

As it turns out, this was mainly due to a GTK+ bug which is now fixed.  Given
that the buggy version is not shipped in any current distributions, and because
the fix is awkward, I am closing this as WONTFIX for now.
