Yes, I agree, but the interesting part of Evas is the concepts it uses
for drawing things, it is transparent for the developer the way the
widget are redrawn. I just think that I could be nice to try it.

If we have to program all the widgets with Cairo, we could come back to
GTK+ that already uses Cairo and save the widgets programming effort :)
