Fixes for area of interest in keying nodes: no need to wait for the whole

input image to be calculated in some cases, use only actual area which is
needed to calculate current tile.

Seems to be giving some % of speedup. Verified result of keying before
this patch and after this patch and they were identical, so hopefully
now area of interest is indeed correct.
