In the end, switching toolkits wouldn't be a bad idea, but it's not the 
only solution. Some things inside of tk could be improved. Modifying tk 
can be scary, more so if we have to think seriously about bundling alpha 
versions of tk 8.7 together with pd-extended, but the alternative is to 
rewrite large amounts of code (everything using sys_gui or implicitly 
referring to Tcl), which is error-prone, hard to test, and too many 
changes in one chunk.

So, it's not very clear to me which one is best.

I had tried making some changes to Tk 8.5, and it seemed somewhat 
promising. I was getting large speedups for some cases, and large 
slowdowns for some other cases. With more work, the latter could have been 
eliminated. It would benefit most other uses of Tk Canvas in other apps as 
well, so it could be integrated to Tk itself.
