With the obvious exception that a child frame whose visibility is off
should not be considered.  IIUC most applications show child frames only
for a short period of time and make them invisible as soon as the user
reacts in some way or restarts typing.

What does the current glyph matrix of the root frame contain now?  The
overwritten parts or the original ones?  Or are the original parts
stashed away so they can be easily reused when the child frame is made
invisible?
