The new GIF89a format might fit your needs; it allows redrawing only
a small portion of the image, adding plain text at a specific location
on the screen, transparent overlay etc etc.  Check out the GIF89a
pictures from Compuserve with a viewer that supports GIF89a like
VUIMAGE 2.7 or the latest CSHOW.
