[Gegl-developer] new gegl-sampler code (GSoC): maximum expected downsampling ratio

[Nicolas Robidoux]

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 Consequently, this thread is
obsolete (unless changing context_rect dynamically leads to a high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.
