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

d5a706e47e better behaviour for truncated PNG files 
truncated PNG files failed with an error, even if --fail was not set ...
instead, just warn, and only error out if fail is on

d7da3c7de7 fix vips_resize() bug 
if hscale and vscale were very different, resize could fail with "reduce
factor too large" ... just a silly typo

205fb817e8 change three C API funcs to match Python/C++/CLI 
vips_math2_const(), vips_boolean_const() and vips_relational_const() had
the const and oper args reversed from the Python/CLI/C++ API

add something to check for arg priority conflicts and resolve the
conflicts it found

4bbd56fb0a handle transparency in vips_region_shrink() 
we weren't multiplying through alpha in vips_region_shrink(), causing
fringing on pyramids with transparent elements

thanks sickrandir!

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

36761bcfd7 make vips_gaussnoise() pixels reproducible 
previously, pixel values were regenerated on every calculation, so they
changed on recomputation

pixel values are now generated from the pixel (x, y) coordinate plus a per-call
seed

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

c5e675f7db fix --vips-cache-max etc. 
--vips-cache-max, --vips-cache-max-memory and --vips-cache-max-files were not
working and probably hadn't been for a while

vipsthumbnail.c turns off the operation cache, it's not useful for
the same operation repeated across many files
