These two headers should always be separated from the others by a blank line.

Done.

m_translate && m_translate->is3DOperation()

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

Perhaps
if (m_translate && m_translate->is3DOperation())
  return true;
..
return false;

OR

return (m_translate && m_translate->is3DOperation())
  || ...

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

Done.
