doesn't this work without the check?

[soonm, 2015/06/10 04:09:32]

Done.

[Eric Willigers, 2015/06/05 01:58:23]

otherwise should we clear the translate property?

Same for rotate, scale

The translate property is initialize to nullptr. If the parentStyle doesn't have
a translate property, then it should be correct.
