/*--------------------------------------------------------------------------*\
* 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().
