You are talking about display() recursively calling the same method of
the childs? Seems the only way to do it to me...
And what performance problem do you see?

passing the mask child to renderAsMask() ? I doubt that would work..

Which way goes the reference between mask and maskee? The mask having
a reference to the maskee or vice-verse?

If the maskee has the reference to the mask, then it would be simple:

- (in dlist.cpp) when a child is found with a mask reference:
- beginMask
- call display() of the mask instance
- endMask
- call display() of the maskee
- disableMask

Just guessing...
