[cairo] Text performance on windows?

[Gerdus van Zyl]

Please see this discussing on the list:

http://lists.cairographics.org/archives/cairo/2008-February/012982.html

The reason I saw slow rendering was with the way I did double
buffering and the type of surface I created. If you could show us your
text rendering code it would be informative.
