1) Is it possible to inquire from a window as to it's background pixmap?

2) Is it possible to get info from the X server about the physical
dimension of the display, like the actual size (in meters, inches
etc.) of the display;  and/or the aspect ratio of the pixels?

I ask these questions because 1) THE HP toolkit requires the
application to tell the toolkit what background pattern is being used
by the window, even after having already told X at window create time.
It would be nice if the toolkit library could get this info from X.

2) The physical attributes would help in implementing libraries like a
GKS library.  How can one implement an isotropic graphics application
without knowing the true aspect ratio.  Also how can one really tell
the point size of a font without knowing physical dimensions.  There
are cases when a display should be able to exactly show the true
dimensions of an object, (perhaps a printed page emulator).
