ximgview is a simple X11 image viewer for 32-bpp BMP images, as
can be created with the 
PNG and
cairo drivers. The display is
continually refreshed.
The display driver must be configure to map the file, with
GRASS_RENDER_FILE_MAPPED=TRUE. This ensures that the file will remain
a constant size, rather than being truncated whenever it is updated.
(bash shell syntax)
export GRASS_RENDER_FILE=map.bmp

export GRASS_RENDER_HEIGHT=480
export GRASS_RENDER_IMMEDIATE=PNG
