Yes I agree this would be how we'd structure it.

Hmmm, that's probably not too big a deal, we'd need
to look more closely at it.  And there's likely code to be shared
which isn't associated with the widget hierarchy, like say the mapping
of color names and font names to values, etc.

On the practical side, since targetting a lower JDK
level and splitting the plugins along certain paths for the eSWT
community is work, this makes sense iff the eSWT community
is committed to contributing.

Aside from all this, are there footprint concerns
for using CSS in embedded?  At present the CSS work isn't small (our
code), and there are quite a number of dependencies.  Batik isn't
structured in a CSS consuming friendly manner and pulls in tons.  Plus
I have no idea if the required JDK levels for all those dependencies match
what you need.  Have you investigated these aspects?  I gather
from your comments you have some previous experience in applying Batik
to embedded.

I personally would find the Multi-touch and gestures
work quite interesting (!!) but not sure of the interest match for e4.
