NSScrollView responding to changes in alpha

Interestingly, NSScrollView in an NSPanel HUD window can have its background color set with alpha and transparency is easy to achieve. Inside a normal NSPanel or window, the backing of the contentView rect seems to be all that will mix with the background color alpha.

Ideally, I'd like this same behavior with a non-HUD panel or window. Also, HUD panels seem to want to remain in front. Does anybody know a quick way to disable that?
