I want to add preferences for sets of prefixed properties (which are going to be among the more difficult prefixes to get rid of) as a way to ease the path towards disabling those prefixes.  This will allow:
 * authors (or other testers) to test what happens when the prefixed property support is removed
 * easy landing and backout of the final patch in case we have to slip it across releases

Add preferences (defaulting to enabled, for now) to control whether certain prefixed aliases for CSS properties are supported, so that authors can have a way to test what happens when they're turned off in advance of our disabling them.  ()

Should this have tests?

FWIW, I plan to blog about this (assuming I remember) after it hits the release channel.
Ms2ger discovered (and I verified) that turning this on breaks styling of tabs in Firefox 20. :-(

, patch 2:  Also condition @-moz-keyframes parsing on the animations preference.

Not surprising; our UI has a tendency to use -moz-prefixed stuff before the unprefixed versions are available.

The good news is that we can easily search-and-replace our UI. ;)

If this is backed out it probably should not be set to RESOLVED FIXED.
The bulk of it is still fixed, just the one thing I missed that's not.
