the notify signal, should be for all properties that can change run time, no matter who is changing it (and of course the object itself is able to know in any way when the property changes to be able to reliably signal it).

the use case is property binding: if you have many classes that are binded to a property, you want all of them immediately automatically updated with the new property value.

an example that doesn't necessary make sense per se but exemplifies, 3 instances of Text {text: framesvgItem.imagePath} should always have the"right" text
