NAME
pushviewport - duplicates the current viewport
SPECIFICATION
C pushviewport()
FORTRAN subroutine pushvi
DESCRIPTION
The current viewport is the top element in a stack of
viewports. pushviewport duplicates the current viewport and
pushes it on the stack. After pushviewport executes, there
are two copies of the current viewport in the stack; you can
change the top one without losing the old one. In addition,
it saves the screenmask and the parameters specified by
setdepth.
