RichTextArea supports a basic and an extended feature set:

http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/ui/RichTextArea.html

I imagine this approach was taken because the RichText capability gap
was too large cross browser to feasibly emulate everything in the
worst browsers.

Would it make sense to take the same approach with GWTCanvas?  (The
vector graphics capability gap between IE6 and FF3 may also be too
large to be feasibly spanned via emulation alone).

For example, Client-side GChart has gained a lot of value from this
relatively small subset of GWTCanvas's features:

http://gchart.googlecode.com/svn/trunk/doc/com/googlecode/gchart/client/GChartCanvasLite.html

Many flowsheet simulation packages could also be comfortably
implemented via some such subset (plus the standard GWT Widgets, of
course). If such a bifurcation allowed GWTCanvas to graduate from the
incubator much faster, I think it would be worthwhile.
