GtkStyle wrapping problem.

[Karl Nelson <kenelson ece ucdavis edu>]

Is there some reason that GtkStyle is not decended from
a GtkObject?  Currently, it is hard to wrap in C++ (beyond
trivial handle) because is don't not have any hooks to tell delete
extra data to.  On objects derived from GtkObject we can
either tie into destroy or use full connections to delete
any wrapper data.  GtkStyle is the exception.  

Is there some reason for this?
