      In other words, the number
    of direct text/overlay props, display specs, face attributes, etc which
    Emacs would have to check now are not less than the number of direct
    properties to check with my approach.

That is true, but it isn't really the point.  Emacs can efficiently
check many face attributes because it does not have to go looking for
them in a list of other things.  By contrast, Gerd found that the
number of different text properties that the redisplay code needs to
look for was crucial to the efficiency of redisplay.

Perhaps someone could find a more efficient way of handling numbers
of text properties.  I don't know.
