I didn't mean that programs should not be able to find out the size of
a window, and when it changes.  I meant that if a program doesn't say
to the windowing system, "Hey man, I'm a whiz bang program, and I
won't freak if my window changes size", then the windowing system
should keep track of a logical and physical size of the window.

If a program tells the windowing system that it is a whiz bang program,
then the program would be informed of size changes, and there would be
no difference between the logical and physical window.
