No, all that was within the performance loop was the RenderBezier 
function. The only reason I called the gdk_* functions was to get 
something to draw on the screen to visually verify that the drawing had 
competed correctly.

The version of Cairo this code was developed for seems to date from 
earlier April 2005 (the latest comment in ChangeLog was 2005-04-12), 
which does seem to be pre version 1.0.
