we're following the hierarchy of any component of the DisplayList.
Consider a long long hierarchy ending with a big park of childs.
For each of the elements in the park:

                bool renderAsMask = ch->isMaskLayer();
                while(!renderAsMask && parent)
                    renderAsMask = parent->isMaskLayer();
                    parent = parent->get_parent();

All the characters share the same parent, btw, so the parent's
scan isn't really needed to replicate for *each* character.
There could be an hineritance scan outside the loop for example.
(less painful change)
