Tim,

  My understanding is that PMX performs not only the standard MIT X server
functions, but must translate the X-windows actions into the equivalent PM
actions.  Apparently this intermediate layer has the floating-point code in
question.

  I believe the PMX developers are working hard to improve this situation, as
each revision makes considerable improvement on its predecessor.
