Some recent painting-efficiency fix broke the inspector, which accidentally depended on things getting repainted too often, and so was failing to highlight things properly now. A simple queue_redraw() fixes this, but while I was there, I decided to port the drawing hook to JS as well, since all the necessary parts of cogl work fine from JS. https://bugzilla.gnome.org/show_bug.cgi?id=642058
