They're more focused on 2D and 2D with effects (the so hated 2.5D),
not pure 3D as in full opengl. I don't know their reasons, but after
iphone came out people want these kind of things and they deliver. And
yes, they can do much more than Evas, because Evas just do colorizing
and scaling, no rotation, blur or transformation matrix (I was
supposed to work on that, but no time atm).

One of the things that clients "love" about Qt features is the ability
to customize things using CSS. They find it very easy because they can
reuse previous skills... It is something easy that Clutter/GTK could
easily use in future. For gtk it's more a matter of changing the
syntax.
