Some things are a lot slower, but some are faster, in my very limited
experience...

I am doing some comparisons of gdk-level functions (because that's what my
app does). I posted some interim comparisons a while ago based on v1.3.10 to
 http://www.cat.csiro.au/cmst/staff/cameron/GDK/alltimes.html
and I have now redone them for  V2.0 and updated the page. They have
improved a bit over the 1.3.10 but the major differences are still present.

My next step is to attempt to do the same benchmarks using native Win-32
graphics ops to see what baseline I should expect. However that will take me
some time, since I've never done Win-32 stuff before. Can anyone direct me
to some sample code for trivial ops like drawing pixels, lines and
rectangles?

I presume none of this is of any use to 95% of GTK apps, since they will get
held up on other bottlenecks, which my tests are not looking at.
