Hey, the new http://code.google.com/webtoolkit/doc/latest/DevGuideUiImageBundles.html is great.
I have a good idea. What is you could use svg ? I wrote a demo using inkscape and c#. But i have given up on c# and asp.net and are now using gwt :) You basically layout ALL the graphics in ink scape, and then you can access parts of it from css ? This actually allows you have some parts of the web page in SVG, and other parts as images, BUT they all are authoured in inkscape as svg. The build process reaches into the SVG and with some extra meta data construct the image bundle and svg bits and pieces. And its all accessible from css. The developer and designer usability and workflow aspects are really HUGE !! -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
