Thanks Alan.

I used the wrong name.  Render is the undesirable extension then
for a "thin profile" of graphics adapter - for performance the
graphics acceleration needs to be near the display, whereas for
a stateless thin client it is not.  Once upon a time Render was
largely only used when available, now more and more
functionality seems to depend upon it being available.
