You might like to check out http://apptree.net/gczoomview.htm which
has all the basics of zooming handled, and could be pretty easily
configured to do what you want.

I am using scaleUnitSquareToSize to zoom out / zoom in on a design
being created in a subclass of NSView.
After calling:
- (IBAction)zoom:(id)sender {
NSSize sz = NSSizeFromString(@"{0.75,0.75}");
[self scaleUnitSquareToSize:sz];
[self display];
}
.. the view scales and moves toward the view origin. This is
expected behavior.
I am looking for a recommendation on how to keep the 'zoomed'
contents in the center of the view.
Should I do a CGContextTranslateCTM before calling -display? Is
this the proper approcah?
