First, thanks for many experiments.

I understand users want to know the size of each monitor rather than
the total size.  But that does not justify changing existing common
functions in an inconsistent and ad hoc way and making them
platform-specific unnecessarily.  If such functionality is necessary,
it should be provided in a platform-independent and consistent way.
