Title: mostly remove the svg onClick hack

- chrome no longer throws a security warning when trying to read pixel
data on a canvas after drawing *any* svg; only svgs with a
tag in them
- Standard Safari is still an old enough WebKit that it has this problem,
but WebKit-nightly (SVN r173347) does not.
- instead of the blanket check, just try it and catch errors
