Adam Turcotte has communicated to me that he is pretty sure that context_rect can be changed dynamically. Consequently, this thread is obsolete (unless changing context_rect dynamically leads to a high speed penalty), because the largest context_rect for the suggested method is not so large so as to "stick out" of the fetch_rectangle.
