I getting ready an animation package for the ST.  We want to start selling it
this summer.  It uses charactor based animation and is fully 3D.  This program
is not a cad program and is very different than CAD 3D (a great program) and
is not a ray tracer.  Anyway I deciding with programs I should support that 
that they will work with the program I'm working on. (Animator:Apperentice
which was written by Martin Hash, I'm adapting it to the Atari ST)  

This program requires a paint program to make it really useful.  So I'm trying
to get a handle on which paint programs I should support.  I don't want to do
more than is needed yet I want to have a reasonable choice for the user.

So far my short term goals are:

        1. work well with NeoChrome and Degas
        2. work well with Spectrum 512 (this is the program I'll hope my 
           user use as 512 color displays are really nice for animation) 

A few months down the road I want to also be compatible the CAD 3D and  Cyber
Paint.  

Is that enough are do people need other support.  I don't what to support
something that only 1 or 2 people need, yet I want to cover the bases.  So
far I'm not impressed with the more than 512 color displays and am steering
away from them.  So what paint programs are people using?
