Signal ID
Connect to CreateContext signal.
The ::create-context signal is emitted when the widget is being realized, and allows you to override how the GL context is created. This is useful when you want to reuse an existing GL context, or if you want to try creating different kinds of GL options.
If context creation fails then the signal handler can use gtk.glarea.GLArea.setError to register a more detailed error of how the construction failed.
