Andy Wingo 9640db9fe2 gst/gstghostpad.h (GstProxyPad, GstProxyPadClass, GstGhostPad)
Original commit message from CVS:
2008-10-08  Andy Wingo  <wingo@pobox.com>

* gst/gstghostpad.h (GstProxyPad, GstProxyPadClass, GstGhostPad)
(GstGhostPadClass): Publically expose these structures so as to
allow easy subclassing from C. Hide the member data behind a
private opaque data pointer.

* gst/gstghostpad.c: Adapt to store instance data in the type
instance's private data region, not in the public struct.
