//--------------------------------------------------------------------------
// Define structure containing pointers to device dependent functions.
//
// pl_MenuStr Pointer to string that is printed in device menu.
//
// pl_DevName A short device "name" for device selection by name.
//
// pl_type 0 for file-oriented device, 1 for interactive
// (the null driver uses -1 here)
//
// pl_seq The sequence number for ordering the presentation list of the
// available drivers. This is an ordering only, not an absolute
// position in the list.
//
// pl_init Initialize device. This routine may also prompt the user
// for certain device parameters or open a graphics file
// (see note). Called only once to set things up. Certain
// options such as familying and resolution (dots/mm) should
// be set up before calling this routine (note: some drivers
// ignore these).
//
// pl_line Draws a line between two points.
//
// pl_polyline Draws a polyline (no broken segments).
//
// pl_eop Finishes out current page (see note).
//
// pl_bop Set up for plotting on a new page. May also open a new
// a new graphics file (see note).
//
// pl_tidy Tidy up. May close graphics file (see note).
//
// pl_state Handle change in PLStream state
// (color, pen width, fill attribute, etc).
//
// pl_esc Escape function for driver-specific commands.
//
//
// Notes:
//
// Most devices allow multi-page plots to be stored in a single graphics
// file, in which case the graphics file should be opened in the pl_init()
// routine, closed in pl_tidy(), and page advances done by calling pl_eop
// and pl_bop() in sequence. If multi-page plots need to be stored in
// different files then pl_bop() should open the file and pl_eop() should
// close it. Do NOT open files in both pl_init() and pl_bop() or close
// files in both pl_eop() and pl_tidy().
