GdkPixbuf types

[Mark Patton <mpatton jhu edu>]

Hi,

I'm working on some language bindings and noticed
a number of types in GdkPixbuf have not been registered.

Specifically: GdkColorspace, GdkPixbufAlphaMode, GdkInterpType
GdkPixbufFrameAction, and GdkPixbufFrame.

Would you accept a patch that registered these types?
I'll just add them to gtktypebuiltins_*.
