Specifications

    1 - 4 frame buffers
    frame buffers any size, selected from config file
    all N frames are the same size
    frame buffers are 8 bits deep

    each frame buffer has its own independent zoom/pan, colortable, wcs, etc.
	attributes


Frame Buffer Strategy

    Frame buffer pixel array is a gterm raster (ximage)
    Memory model: fast nice-to-server small

    If server pixmaps are being used the frame raster is mapped to a gterm
	server pixmap raster the size of the display window
    The server pixmap raster is mapped to the screen with a 1-1 mapping
    Zoom and pan are controlled by the ximage->pixmap mapping
    The frame being displayed is controlled by the pixmap->screen mapping

    If server pixmaps are not used the first raster will be mapped
	either to another ximage raster, or directly to the screen.
	The first option still provides a reasonable blink capability,
	the second will be slow if zoom is in effect.


Program Structure

    main
	obm <- gui file
	    gui program
	    widget tree
	iisio
	    gterm widget


    The GUI program handles:
	keyboard and function key input
	pointer input
	frame selection, blink, zoom/pan, colortable selection, windowing
	control panel options

    The IISIO section handles:
	communication with the client
	frame buffer configuration
	read/write frame buffer
	frame selection
	cursor readback
	

Optional features
    Magnifier - region under the cursor
    Split screen - controlled by popup control panel
    Split region - display alternate frame in region under cursor
    Zoom box - display de-zoomed or zoomed subregion in a marker
    Load/save file (sunraster or fits)
