Pay no attention to the man behind the curtain :-)

The exact behavior is implementation dependent, but the reality is that
Level 1 implementations of DPS always use halftones in images.  There is
no way to avoid the dithering.  Level 2 systems, which will be coming out
eventually, will not have this limitation.

Just to correct another small mistake in Steve's posting so that mistaken
information doesn't propagate, the "actual" parameter to XDPSCreateContext
is an integer indicating how many actuals you want allocated, not a Boolean
indicating whether to allocate them.  It is just a hint, and some DPS/X
implementations ignore it, so you should not depend upon it for anything.
