GtkTableChild publc API

[Murray Cumming <murrayc usa net>]

GtkTableChild seems to be a semi-public struct, used as the items in the
GtkTable::children GList.

The documentation describes some of the struct fields, but I'd like some
official confirmation that all of the GtkTableChild fields are kinda
public API. And I wonder when it would make sense to change any of the
values, and when those new values would begin to be used.
