Dirty rect invalidation issues in mozilla sample
http://www.croczilla.com/svg/samples/opacity2/opacity2.svg

This could be one of many things:
1.  Integer vs. Float rounding issues: http://bugzilla.opendarwin.org/show_bug.cgi?id=4462
2.  QRect-of-by-one problems: http://bugzilla.opendarwin.org/show_bug.cgi?id=6026
3.  Or sometimes using the fill-only bbox, vs the fill+stroke bbox (or having stroke bbox calculations be 
wrong).

Mouse over the green hexegon and then back out (w/o mousing over the star).

This is a basic invalidation issue which will be highly visable to users.  We could not ship an SVG implementation w/o fixing this bug.  Adding SVGHitList keyword and bumping to P2.

svghitlist was seemingly lost? this is an important one

Proposed fix

There are lots of invalidation problems left, but this should fix
the problem at hand.
