scaleUnitSquareToSize

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?
