- The problem with CairoWidget was that it did scale a pixmap of ~100x100

with a *factor* of ~640x480. That means ~64*48*10^6*3 bytes = a ~1.1 Gb RAM pixmap.
The problem didn't show in versions of cairo >= 1.2 because it automagically
clips (yeah, cairo programmers *are* smart :-))
It is temporary fixed for the moment, will be made better asap.
