NSWindow can animate its frame changes, and you can register for

before/after frame size ratio, rather than drawing the actual window
content. Notice that the System Preferences window is a fixed width,
and as each new pane fades in, it stays attached to the window origin
in the bottom left when animating the frame... simple? ;)
Yeah, pretty simple. Thanks to you and Scott for pointing out the
OpenGL and NSImage solutions. I guess OpenGL would be faster among the
two (at least until Tiger and CoreImage arrives *drooling* ).
Yours sincerely,
