7938903d22 don't size caches by image width 
we were sizing buffers partly by image width, which could cause caches
to be too small if width changed down a pipeline

7136053451 sort max/min results by y and x coordinate 
previously the list of maxima or minima found by max/min were in found
order, so essentially random

they now sort equal values by y then x coordinate, so the results are
consistent between runs, provided there are fewer maxima / minima than
are being tracked

fa3c92c19b add CLAHE 
vips_hist_local() has a new param, max_slope, which sets the maximum
amount that the local contrast can be boosted by -- CLAHE

see https://github.com/jcupitt/libvips/issues/268

also fix a couple of small range problems

- scale by 255, not 256, to avoid an overflow
- cum hist includes the current value, so sum to <= target, not < target
