I've added to cvs for 5.0 and 5.1 a toggle button in the wxt tools widget.

The very first time you use it, the state of the toggle button may not be
reported correctly because the corresponding state variable doesn't exist
in your previous saved-state file.  But once you've exited the program
that first time, causing the saved-state to be updated, everything should work
correcly in subsequent sessions.

I also have code to add save-to-png-file to the wxt toolbar.
But I haven't worked with this toolkit before and I haven't found a
decent worked example to show how to embed this in a pull-down menu. 
So as before ...
