1024x768.

Understood for ordinary use, but plscmap1() is invaluable for dealing with
colour paletted images so this functionality should be retained.  However, I
agree we shouldn't demo plscmap1() in example 8, and generating gray scale
with two control points is a more beneficial example for the newbie user.

Good.

Thanks also for the additional information you gave re cmap0 and cmap1
palette files.
