From Konstantin Matveyev, "I've changed osg::Uniform::Callback to osg::UniformCallback.

osg::UniformCallback inherits osg::Callback now.

I don't really now if this class should be inside osgWrappers/serializers
because StateAttributeCallback is not presented there, but i've included it in the patch.


Please see archive in the attachment.


PS
DEEP_COPY_UNIFORMS works for me.
"
Note from Robert Osfield, added typedef UniformCallback Callback for backwards compatibility.
