As promised, and only a month late. My branch is available at,
https://gitweb.michael.orlitzky.com/libsvgtiny.git libcss
For best results, you should also apply the libcss patch I recently
posted that makes fill- and stroke-opacity inherited properties.
No major issues remain. There's a test suite in test/css consisting
of a bunch of SVG files that you can open side-by-side in the
libsvgtiny example program and your favorite image viewer. With the
libcss patch, they all pass (compared to firefox). Without it, two
fail.
If you recall, there was some concern about the licensing of the
select handlers. I think I spent enough time learning and rewriting
the handlers to alleviate those concerns; I ultimately did not copy
anything from NetSurf, although naturally many of the handlers look
similar (and of course I reimplemented them *after* looking at the
NetSurf handlers, so you be the judge).
A summary of the changes follows.
