Hi Liam,

If you look at my benchmark, that is the 1st of the two tests being
executed:

<snip>

FOR I = 0, 49 DO BEGIN
  WSET, pixmap0_id
  TV, data, true = 3
  WSET, pixmap1_id
  DEVICE, COPY = [0, 0, sz-1, sz-1, 0, 0, pixmap0_id]
ENDFOR

<snip>

Also, the results I posted show no difference between the technique
that you describe and just TVing directly to the visible window.  Ten
fps at 512*512 would be great but I see no indication that I can
achieve that on a PC.  BTW, this benchmarking is in preparation for
what will be the SW end of a generic (any format) video frame grabber.
 Could you verify if the snippet above is what you had in mind?

Thanks a bunch,
Bill
