Device-independent routine for setting up the viewport. This defines
the viewport in terms of normalized subpage coordinates which run
from 0.0 to 1.0 (left to right and bottom to top) along each edge of
the current subpage. Use the alternate routine plsvpa in order to
create a viewport of a definite size.
xmin
(PLFLTThe normalized subpage coordinate of the left-hand edge of the viewport.
xmax
(PLFLTThe normalized subpage coordinate of the right-hand edge of the viewport.
ymin
(PLFLTThe normalized subpage coordinate of the bottom edge of the viewport.
ymax
(PLFLTThe normalized subpage coordinate of the top edge of the viewport.
Redacted form: plvpor(xmin, xmax, ymin, ymax)
