58f9757467 fix transparency detection in merge
a typo meant we were just testing the first band for zero, not all three

- we are writing a cmyk image
- there is an embedded profile
- the saver does not support cmyk

6a189d068b mark vipsprofile as python2
Some distros have python3 as the default, so make vipsprofile explicitly
python2, thanks ioquatix.

7b64246af2 fix a couple of issues with huge profiles
The base64 encode limit was 1MB, but some huge profiles can get over
that, so it's now 10MB.

transform_save_string_blob() was incorrectly setting a refstring not a
blob as an error fallback, potentially leaving a dangling pointer.

Thanks Jaume!

942b0446a3 revise fail handling, again
clarify policy on file read errors and warnings:

* if the file format library reports a warning, we log it in vips, but
that's all
* if the file format library reports an error, we log it, but try to
continue
* if the file format library reports an error and fail is set, we log it
and fail

all loaders now implement this

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

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

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
