It is my understanding from reading the CLX documentation for X11R2 (and from
experimentation) that it is not possible to specify a gcontext tile pixmap of
depth 1 for a draw-rectangle operation to a destination of depth N, N > 1:
  "The tile pixmap must have the same root and depth as the graphic context."

This, of course, requires me to have a tile pixmap of depth 1 AND the same tile
pixmap of depth N if I expect to run my system on both depth 1 and depth N
displays.

Is my understanding in this case correct?  Can someone give me a rationale for
this design decision?  Thanks for any information.
