Hi,
I contact Flute author to know if it is interested to improve it and manage CSS3, like I have started to do.

I'm not sure why we'd want to write
our own SAC parser. Its a lot of work and there are clearly existing technologies
which, while maybe not perfect fits, are better than starting from scratch.
I'd much rather work with an existing
community supporting Flute or Batik (assuming such communities exist, the
Flute files are all 2002 so not clear if its dead code or not). Just
as with Eclipse, you see if the community is open to making the changes
you need. If they are, you help make those changes. This gets you
the technology you need, and meanwhile furthers that community. Everyone
wins! And its a very efficient use of developer resources which are
always scarse. I'd rather spend those cycles doing something more
specific to Eclipse (like nice style sheets, like a UI model, etc.).
Regards,
Kevin
Yes, and maybe not only a parser.
SWT burden lots of legacy, which I not known about, and nice to hear details.
