Why?  This seems to be a compile-time thing.  We can discover if the
build system has X11, or is Windows, or is OS X, and then we just need
to know how to get the screen characteristics on those systems.  I
provided the example code for X11.  Now someone else needs to do the
same for Windows and OS X.
