From: L. David Baron <dbaron@dbaron.org>

Bug 837211:  Off-by-default preference for testing the effect of supporting -webkit- prefixes or unprefixed properties.

FIXME: Test that names are all correct

FIXME: Add aliases for transition/animation events.

FIXME:
<dbaron> bz, were you aware that Webkit accepts element.style.WebkitTransform or element.style.webkitTransform (either case), but only lowercase shows up when you enumerate?
<bz> dbaron: no, I was not
<bz> dbaron: I knew it accepted element.style["-webkit-transform"]
<bz> dbaron: that's interesting....
