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

3019e5966b vips_conv*() default to float
we had INT as the default, but this will cause serious precision loss
with many masks ... instead, have float (always correct) as the default
and let people turn on int if they cn

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

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

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
