To my knowledge, there is the CRIMP package by Andreas Kupries.

https://core.tcl-lang.org/akupries/crimp/home

And I would love to get the image code a loadable extension of Tk, so it 
may be loaded without Tk.
I already looked into this. It is far from trivial, as there are many 
direct interaction between widget code and core image code...

And I would love to remove a lot of old stuff from the image code. We 
missed this with Tk 9.0...

Any help appreciated...

Thanks,
Harald
