[Bug 1483089] [NEW] Changing zoom causes view to be lost

 

Public bug reported:

Currently, changing the zoom setting generally causes the view of the
image to change drastically. It would be more intuitive and save on
scrolling/searching if it preserved the center pixel of the previous and
new view.

The image viewer in both the masks and control points tab seem to behave
this way. I tried the 2013 and 2014 release version on OS X. I'm pasting
the System tab information below.

Thanks in advance for looking into it :)
