[GM-core] ChannelThresholdImage interface

ChannelThresholdImage is considerably faster due to the latest code
updates (in CVS).

Unfortunately, I don't like the functionality of this routine very
much.  The thresholding is specified like 'threshold' (e.g. "30%"), or
'red/green/blue/opacity' (e.g. "30%/40%/50%/60%").  The problem with
this interface is that *all* channels must be thresholded.  It would
be nice if the user could specify channels to ignore so that only one
or two channels could be thresholded.

Does anyone have an idea of how the current syntax can be supported
while also being able to specify that a channel should not be altered?
