A user left a comment in the Magnifier documentation:
I added a MouseWhell event so that the magnifier can zoom in or out by rotating the mouse wheel. It appears that the magnifier zooms in/out based on the upper left hand corner of the magnifier not the centre where the mouse is. resulting in the magnified area scrolling down/up Shouldn't the magnifier uses the position of the mouse, the centre of the magnifier as its transform coordinates.
----
That need is interesting and could be implemented as a feature.
