Some GstAppSink functions have incorrect return nullability in Vala
GstAppSink.pull_sample() and some other fucntions specify non-nullable
Gst.Sample in the docs and bindings when in reality, the return is nullable and should be
Gst.Sample?. I'm not very familiar with GObject annotations but perhaps the problem lies there?
