The inspector may hold on to render nodes and textures beyond the lifetime of the widget (and thus the GL resources). To handle this situation, allow the widget to explicitly release the GL resources, and make the texture available on the clent-side as a cairo surface. This lets the recorder still show the content after the widget is gone.
