Zooming images is now implemented in a very early phase.
Things yet to do in this regard:
	-	 zoomFactor range should be computed relative to the picture size and to the space
     available to the widget. When initially loaded, regardless of their image dimensions,
     the image should fill the space given to it on one dimension (max(W,H)).
	- zooming with mouse scroll over scrollArea
  - panning with the mouse in scrollArea

Should be sexy enough with that :D
