   That is a concern for sure.  My take on that at the time was that there have   
   probably been maybe 10 animated ANSIs worth viewing in the history of ANSI art   
   and that modern buffering on TCP/IP and terminals could also make ANSImation   
   inconsistant.  I felt the benefits far outweighed the ANSImation issue.   
      
   I do have an "undocumented" command that will do a raw message dump to the   
   screen without any pre-processing which would allow ANSImation in those rare   
   cases, but so far no one has ever brought this up.

   I am adjusting it.  So a 1;1H would translate to the top of the message view   
   and not actually the first row and first column of the user's terminal, and   
   then any cursor movements are offset like that as well.   
      
   It doesn't use any terminal-based boundaries/scroll regions but the end result   
   is about the same as if it did.

   It was a lot of work.  At the time I was driven by some cooler ideas like the   
   art collaboration through message bases. None of that was ever used though, so   
   at the end of the day it is probably most noticed when someone posts an ANSI   
   with a clear screen lol.   
      
   I don't think the effort to build something like that is worth it if its just   
   for that clear screen "use-case" (if you can call it that).
