   PetscDrawRealToColor - Maps a real value within an interval to a color.
   The color is an integer value in the range [PETSC_DRAW_BASIC_COLORS to 255]
   that can be passed to various drawing routines.

   Synopsis:
   #include <petscdraw.h>
   int PetscDrawRealToColor(PetscReal value,PetscReal min,PetscReal max)

   Not Collective

   Input Parameter:
+  value - value to map within the interval [min,max]
.  min - lower end of interval
-  max - upper end of interval

   Notes: Values outside the interval [min,max] are clipped.

   Level: intermediate
