porting from SGIs to Linux?

[Peter Bismuti]

I'd like to port some applications from SGIs which use a Motif/ViewKit UI to 
Linux machines running RedHat.

These applications rely on pseudo-colors.   My first question is: is there a 
simple way of doing this?  Is there some last simple function that can be 
applied to the final pixmap that can alter the colors of the drawing?

The opinion has been expressed that PC hardware will continue to not support 
psuedo-colors, and to abandon psuedo-colors all together.  Perhaps the 
performs penalty will ultimately be a motivation on the long term?  However 
some applications may not even be alive before that happens.  Is there a 
temporary solution?

So my second question is, I've heard that the new X.org release offers 
software support for pseudo-colors?  Could this be used to at least display 
on a Linujx machine while these apps while running on an SGI? If so, how can 
the issue of the Motif/ViewKit code be handled?  There no longer seems to be 
a free version.  Just pay for the commercial version?  Port everything 
supported by Mesa, i.e. LessTiff?  This is a lot of work I'd prefer not to 
have to do.

Even help?
