I think it would be better to use Canvas for this. 

Indeed, there are many weak aspects to the tkobjc library, but I'm
afraid I already spend too much time on these tangential GUI features.
However, the tkobjc library is fairly simple code, and any Tcl/Tk manual
should be sufficient information to make whatever enhancements you want.  
One of the main reasons we share the source code to Swarm is so that
users can do this (and hopefully share their changes with the community).
