it's weird, because the class is marked as deprecated: https://git.gnome.org/browse/clutter/tree/clutter/deprecated/clutter-rectangle.c?h=clutter-1.16#n26 it used to be propagated to all symbols on that class. it probably has to do with the fact that we're not using global pre-processor symbols, and instead we're using compiler annotations. I'll open a bug so that I don't forget to fix this before the next release. > The incomplete tutorial - which I have to fix after this new discovery - > should be available here: http://goo.gl/LkQUfy > > **Any comment is highly appreciated** (I believe you can comment directly on > the document if you have a Google Account). thanks!
