In case it turns out to be difficult to set the context_rect to be variable (set on an output pixel by pixel basis--Eric is looking into this), I'd like to know what I could assume is the largest reasonable downsampling ratio, meaning that larger downsampling ratios would be clamped down to this ceiling. Such clamping would allow us to set the context rectangle to a (reasonably small) fixed value. More specifically, could I reasonably clamp the downsampling ratio (in each direction) to one of the following values? 1.0 (context_rect.width = 4) 2.7182818284 (context_rect.width = 5) 7.3890560989 (context_rect.width = 6) 20.0855369231 (context_rect.width = 7) 54.5981500331 148.4131591025 403.4287934927 1096.6331584284 2980.9579870417 (context_rect.width = 12) (first and last ones included for the sake of completeness.) The smaller the maximum, the faster the code will run. (As the above table makes pretty obvious, the method will be more suitable for mild downsampling that "heavy duty.")
