The actual problem is that current docs say you should use local scope,
so probably people did use it and those will break when we start
using delete :) 

The main thing is that it does need some work. :) (patches are
accepted of course...)

I dont think this works. If someone does gtk_style_unref(mystyle), this impl
just misses that one. => no go. Better go for the finalize thingy mentioned
at previous messages.
