Need to unref context after setting it in GstVideoOverlay ?

[Guillaume Desmottes]

Hi Guillermo,

The context argument of gst_element_set_context() is marked as 
"(transfer none)" in the documentation.
This means the caller preserves ownership of it and so should unref it 
with gst_context_unref() once it's done with it.
