Hi Werner,

This is really down to the requirements of the your app, but in
general if I write real-time apps which constantly render frames, so
an update is never more than 1/60th a frame away.  For interactive
apps the cost of rendering a frame is typically very small so here its
just fine to render the whole frame too.

Robert.
