[Mono-osx] More namespaces, help needed.

[Miguel de Icaza]

Hey folks,

    Someone on twitter pointed me out to a couple of extra namespaces
with interesting stuff that we do not currently bind.

    If anyone was thinking "Man, I wish I could bind some APIs for
MonoMac", now is your chance!

The stuff lives in the Quartz framework, and there are four libraries:
* ImageKit
* PDFKit
* QuartzComposer
* QuartzFilter
