/* Note added by Raph Levien, 27 Jan 1998
This looks it was intended as an optimization, but it seems to
have correctness problems. In particular, if all channels are
turned off, the screen simply does not update the projected
image. It should be black. Turning off this optimization seems to
restore correct behavior. At some future point, it may be
desirable to turn the optimization back on.
