[Mono-osx] Animating Views Example

I added some extensions methods now to MonoMac, so you should be able to
invoke those methods on the RectangleF:

	var newRect = rect.IntegralRect ();

Good catch, I have now added the AppKit specific version, the API stays
the same, but you should not be getting the error anymore.

I have added these missing pieces now, could you try this again with the
new APIs (Animator is the name of the property).

Do you have a sample snippet of Objective-C that you could share with
me?   That would help me figure out where this is supposed to go.
