In PhAB when creating a dialog setup function and indicating that it should
be called “Pre-Realized” that should really be “Pre-Creation” shouldn’t it?
If a dialog is created, a setup function is called and a subsequent callback
says to Unrealize the dialog, and then the dialog is re-requested via a
Dialog type callback, the dialog is NOT re-created but it is Re-Realized.
Yet the “Pre-Realize” setup function is NOT called again.
I realize that where my code called PtUnrealizeWidget( myDialog ) it should
have called PtDestroyWidget() and I fixed that. But I think the PhAB screen
should be fixed.
