Julian et al, when it comes to Cairo and it's infamous lack of rendering speed I have a slight hum of remembering a discussion of why Cairo was so much slower. I cannot understand why it should be so much slower...
There were some work put into finding out why. I found code that implements pixel align. My simple tests using "Analyze->Benchmark" did not give any big difference between pixel align or not (disabled/enable via the #define in draw.c). Is there a simple trick to get it faster? In GTK there are, for instance functions, where you send in lists of objects to draw, and that makes it faster. I use libcairo 1.8. Is 1.9 faster in any way? When it comes to replacing GDK, I think it is a long trip. It might suck but there is a lot of energy put into that. But I for one would like to see a solution of the Cairo slowness to get rid of GDK, because Cairo is so much better in every other way. But more than 5 times slower is not acceptable.
