It has been there forever.  And the UVRANGE code is very simple.  It
should display the UVRANGE it uses on the plot itself unless it
decides to use no UVRANGE.

Note that UVRANGE=30000,0 will not work because uvrange(2) <
uvrange(1) in which case it will do all UVs.

C                                       Test UV range
      NOUVR = .FALSE.
      IF ((UVRANG(1).GE.UVRANG(2)) .OR. (UVRANG(1).LT.0.0)) THEN
         NOUVR = .TRUE.
         UVRANG(1) = 0.0
         UVRANG(2) = 1.E10
         END IF
      UVRANG(1) = UVRANG(1) * 1.0E3
      UVRANG(2) = UVRANG(2) * 1.0E3
