SpaceAnalyzer: Use raw_delta_y in TreeMapWidget::mousewheel_event

Browse source 
There was a FIXME about using raw delta y value of the mousewheel event
in TreeMapWidget::mousewheel_event. Some time after that code was
written, a raw delta x/y API was added to GUI::MouseEvent. This patch
simply uses that API and removes the FIXME message there.
