[vtkusers] Magnify Glass

[Karthik Krishnan]

yes.. the typical way is to display a zoomed version the image, using
a second camera on a corner of the renderwindow, usiing a separate
overlay renderer, or to display it on a separate smaller render
window.

Having a hovered region over the scene itself will just slow the
rendering of the scene itself down as you move the cursor and is
usually not practical.
