I think that a few additional cases can be added to
manual-tests/custom-cursors.html, and a similar SVG test should be added (based
on the attached test?). Some ideas about what to test:
- standard and IE6 (incomplete) declarations should parse OK;
- CSS3 hotspot values should not break parsing;
- fallback should work for both missing images and ones that failed to decode;
- should be able to fallback to a named cursor (implied, in incomplete case),
as well as to a custom one;
- should support SVG cursors (as in url(cursor.svg) and
url(example.svg#linkcursor)).

Google suggests that this may be of use:
http://www.gtalbot.org/DHTMLSection/Cursors.html

The handling of CursorInfo doesn't look quite right to me -
StyleInheritedData::operator==() will not compare copies as equal, because the
address of cursorInfo will be different. Can CursorInfo itself be made
refcountable? I'd also try to use Vector, rather that create a brand new list
implementation.

I haven't reviewed the rest of the patch, so I'm leaving the flag as is, hoping
that someone will comment more.
