pspltrgn - subroutine to set which small plot region to use
This routine is called by pschem in psvdraw_new in order to plot multiple
ternary chemographies on a single page. Each page can hold MAXPLOTSPERPAGE. If
another is requested, then a new document will be created with a name similar to
that of the first, and the process will begin again.
This overrides any settings made in psssc2, and assumes that x and y (real-unit)
bounds are 0.0-1.0. Note that if this routine is called, then plot_aspect_ratio will be ignored.
Note that plotnum is a zero-based index
