Description Ryosuke Niwa 2010-10-18 17:39:12 PDT
RenderTextControl currently has many functions that instantiate VisiblePosition but this may cause layout and destroy the RenderTextControl itself.  We must remove this dependency as soon as possible.
Comment 1 Ryosuke Niwa 2011-07-13 00:53:14 PDT
Now, the only member function of RenderTextControl that uses VisiblePosition is visiblePositionForIndex, which is inherited from RenderObject.  Since removing visiblePositionForIndex from RenderTextControl requires removing it from RenderObject, I consider this to be beyond the scope of this bug.
