Summary:
In a log from someone talking about high CPU we can see get multiple X
events for the same window as multiple events, but directly next to each
other. This causes the TaskManager to process changes multiple times
instead of just once which is a waste.
An example is just pressing "enter" in konsole, which will pointlessly
update the title.
This causes problems for expensive app lookup and also QML performs text layouts immediately so any text changes cause quite large CPU usage if done more than 60fps; especially a task text resizing
could result in resizing the entire panel.
Something not relevant in kwin that also monitors these rolls.
This class sits between KWindowSystem and XWindowTasksModel
transparently buffering the changes.

Summary:
As this happens the screen filtering higher up in the proxy chain
culimating in TasksModel needs to be re-executed, as it compares
ScreenGeometry against a property value set on the model. Without
this update, tasks may disappear from views using TasksModel.
Mapping the trigger conditions to affected rows is deliberately
maximally coarse; see implementation comment in code.

Summary:
Create a subclass of AbstractTasksModelIface which proxies the call to
the source model.
All proxy models can then re-use this rather than duplicating the code
