Fixes: http://bugs.webkit.org/show_bug.cgi?id=12501 (SVG Text fails to respect opacity, fill-opacity and stroke-opacity)
Fixes: http://bugs.webkit.org/show_bug.cgi?id=14045 (Incorrect support for opacity, fill-opacity and stroke-opacity)
Based on an older patch from Rob, this fixes SVG text opacity as well as group opacity for solid fills & gradients.
The pattern changes are still missing a testcase (need to wait for Antoine Quint for that).
