Disable antialising for shapes with shape-rendering="optimizeSpeed"

The SVG spec hints that optimizeSpeed may disable antialising[1] and
this matches Gecko's behavior. This patch disables shape anti-aliasing
when optimizeSpeed is used.

The shape rendering test has been improved to cover all shape-rendering
values, and to include both stroked lines and filled paths.

I hit this again wrestling with Firefox's antialising of a QR code... might as
well fix it because I suspect other people also expect "optimizeSpeed" to
disable AA.

If you like this patch, I'll file a bug against WebKit to make the same change.

This seems entirely reasonable to me. And LGTM too.
