Change only the active instance draw count for an established fixed-capacity pool.
Unlike setThinInstanceCount, this does not mark matrix or color data dirty. Callers that expose
newly written slots must separately mark their exact dirty ranges before the next draw. The pool
must have completed an initial full-capacity GPU synchronization.
