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

[Pierre Alexandre Tremblay]

Dear Miller and Christof

I’m sorry to be the cause of pain - I will amend the patch now but what is strange in this one is that recoding it actually changes its behaviour.

In all cases, I wish I had seen the changelog entry that would tell me how the hidden but essential donecanvasdialog settings / behaviour has changed. In all case, I hope this unexpected behaviour report is somewhat helpful.

I know my desire to stay vanilla complicates things too, but again, so many combinations of hardware and oses I think might justify my self-inflicted pain

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...
