Prevent unneeded fallback

Starting in be8327bd54, we assume that all
exceptions in DoRePaint() are caused by OpenGL.  But many calls in
UpdateItems() will throw if there are internal errors such as
std::out_of_range.  Here, we catch those errors and simply skip ahead
rather than falling back to Cairo
