[PD] Problem with this (involved) abstraction for XY

[Christof Ressi]

Sigh.

@Miller Can we please finally get 
https://github.com/pure-data/pure-data/pull/627? This PR has been 
sitting around for more than 4 years now. In the meantime, people kept 
abusing the private "donecanvasdialog" message in place of a better and 
officially supported alternative, and they will continue to do so...
