d711f98bfb Clean up manual test to QGraphicsView (rubberband)
This cleans a bit up in the manual test by
a) Removing a weird reference alloration (and replace . with ->)
b) rename for variable from v (which was also the view name) to n.
c) remove a big item in the scene rect that is irrelevant to the test

717a0a9d04 QGraphicsView - emit signal when rubber band changes.
The rubberBandRect function is nice to have, but this patch
makes it easier to track the rubber band by emiting a signal
on change.

That makes it easier (and less clumsy/hacky) to show information
related to the rubber band.

c56f73cc1e QGraphicsView - add function to get RubberBand rect
In many situations it is handy to know the rubberband rect.
There are many situations where we want to show something
related to the rubberband.

Regardless how that is done the rubberband area is needed.
(Not having this is a flaw that can force people to do make
a customized rubberband just to get this information)

9cf56b3e09 QGraphicsView - fix rubberband to expand on wheel event
In SHA 51914375b6 the rubberband
selection was fixed, so it followed the scene-point on mousemove.

However wheelEvent could move the view - but avoid update of the
rubberband (that would not be updated until next mouse-move).

This patch fixes that (and generally improves rubberband behavior)
since QGraphicsViewPrivate::mouseMoveEventHandler is called by
replayLastMouseEvent, which is called from various places,
where we need to update the rubberband (e.g scrollContentsBy).

51914375b6 QGraphicsView - fix rubberband to stay right on scroll
We should consider the scene-position when we are expanding
moving a rubberband. If the user does some auto-scroll
(Qt should support that itself, but that is another matter)
then the rubberband should not keep the (old) local position
to calculate the rubberband extension, but instead use the
scene-position that was actually clicked.
