- AbstractTaskItem::paint() is perhaps not the most appropriate place
to publish updated task icon geometry, because this will lead to many
calls during animations when the task icon may only be moving by a
small amount on each call.  With caching enabled (in Qt 4.4) the paint() method might \
not be called when the item is just moving around.  Perhaps publish icon geometry in \
response to the ItemPositionHasChanged graphics item event instead, with publishing \
turned off during layout animations.

- Both TaskGroupItem and AbstractTaskItem implement
publishIconGeometry(), which means that when both the task and the
parent (a TaskGroupItem) are repainted, both will publish icon
geometry for the task.

Regards,
Robert.
