Thanks! Would you consider the first pseudo-code snippet in this link an
applicable illustration of temporary surface use?

On another note, again speaking as an amateur, is there a common reason for
already-rendered items (even if that rendering is slow) to continue to consume
massive CPU, with no user activity at all, as in the current case? That is, is
some level of code re-rendering things unnecessarily?
