Summary Transitions between apparently matching transform values don't always work

Sometimes, transitions between different values of -webkit-transform don't work, even when they appear that they should. The problem is that the TransformOperations blendFunc() is changing the transform ops list out from under us; it is inserting identity operations in place of other operations that happen to be identity (like "rotate(0)"). Because of this, the transform operation lists in the old and new states no longer match by type, and the transition fails to run.
