Is NSScaleProportionally buggy?

I 'think' I've run across a bug in NSImageView.

When my NSImageView window is resized the image I'm displaying in this
window resizes correctly as long as I'm
making the image smaller than the actual image.  If I make the window
larger than the actual image the image will
not get any larger.  ie decimation works but interpolation doesn't.
Is it because I've forgotten or am unaware of a method that needs to be
called so interpolation works?

Hate to say it but this, but is a bug that should have been fixed a
long time ago?
