Original Notes
XIMTOOL
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.
