- There was a posting on this list many moons ago claiming that it is
- indeed possible to have overlapping monitors. The "monitors" control
- panel prevents you from placing one monitor over another, but this
- posting claimed one can edit the system resource containing the
- monitors setup to give two monitors overlapping (or even identical)
- rectangles, and get the descrived behavior.

- I've never tried to do this. In fact, I've tried to think through the
- ramifications for some programs I have written, and decided that my
- programs could sometimes make inappropriate decisions about just what
- kind of graphics to display (for example, CopyBitsing from the 8 bit
- deep offscreen pixmap rather than the 4 bit deep pixmap etc). Thus
- the results one gets may depend on what applications one is running.
- Be warned!
