you really should think less in terms of "lynx" when talking about tgi 
stuff... most targets dont have these features, and a lot of them dont even 
have sprites at all (and another bunch doesnt even have a bitmap mode). tgi 
is ment to support the *least* common denominator of the target platforms, so 
you can write portable programs with it. when talking about tgi stuff its a 
much better idea to think of eg the apple2 and what it can do. if then 
further more advanced features can be supported without adding lots of stuff 
that can not be used by many targets, fine.
