/*
* GSREND.C - high level rendering control for PGS
*
* Source Version: 2.0
* Software Release #92-0043
*
*/
#include "cpyright.h"

/* Rendering Procedure:
*
* 1) Render a linked list of mappings with a single rendering serially
* (uses PG_draw_graph)
*
* PG_make_device (allocate the device)
* PG_open_device (open the device for drawing)
* PG_setup_picture (setup viewport, WC, etc)
* loop over mappings
* render individual mapping (control pixels in viewport)
* PG_finish_picture (dress with axes, labels, etc, and flush)
*
* 2) Render a linked list of mappings with a individual renderings serially
* (uses PG_draw_picture)
*
* PG_make_device (allocate the device)
* PG_open_device (open the device for drawing)
* PG_setup_picture (setup viewport, WC, etc)
* (set device flag to supress setup and finish in subsequent
* calls to PG_draw_graph)
* loop over mappings
* PG_draw_graph (control pixels in viewport)
* PG_finish_picture (dress with axes, labels, etc, and flush)
* (reset device flag supressing setup and finish)
*
* 3) Render a linked list of mappings with a single rendering in parallel
* (uses PG_draw_graph)
*
* PG_make_device (allocate the device)
* (select a node to open the requested drawing device
* all nodes open an IMAGE device and the selected
* node opens the requested device)
* PG_open_device (open the device for drawing)
* (all nodes open IMAGE device and selected node
* also opens requested device)
* PG_setup_picture (setup viewport, WC, etc)
* (call to PG_parallel_setup to communicate common
* viewport, WC, and extrema values in order to limit each
* node to settting only those pixels of the final
* picture for which it has data)
* loop over mappings
* render individual mapping to IMAGE device
* PG_finish_picture (dress with axes, labels, etc, and flush)
* (after usual finish_picture all IMAGE devices
* transmit their raster to the selected node
* (_PG_transmit_images)
* which assembles them into a single raster image
* (_PG_display_image)
* and displays the raster image to the requested device
* with the rendering decorations of the selected type
* (PG_render_parallel)
*
* 4) Render a linked list of mappings with individual renderings in parallel
* (uses PG_draw_picture)
*
