Cleanup GeneratorGeneratedImage/Gradient changes from http://trac.webkit.org/changeset/117858

[Tim Horton]

There are a bunch of review comments from http://trac.webkit.org/changeset/117858 (in https://bugs.webkit.org/show_bug.cgi?id=86906) which I haven't yet taken care of. I have a patch to fix all but one (we still have a timer-per-GeneratorGeneratedImage) of the comments.

If the patch to draw() has been checked in by now, that will need the same cleanup.

return a.xScale() == b.xScale() && a.yScale() == b.yScale()?
