"intent" lets you set the rendering intent for any ICC conversions --
the default is the (more correct) relative, but "perceptual" can look
better

we were only replacing enumtypes if it had changed, but this meant that
make usually thought it was out of date compared to the source files,
and rebuilt it, which needed perl
now we always replace it, so (hopefully) perl is no longer a
compile-time dependency
we were only failing on libjpeg errors, but libjpeg treats very serious
things thaht we want to be able to catch (like truncated files) as warnings
... we must therefore error out if fail is set and libjpeg issues a warning
see https://github.com/lovell/sharp/issues/793
If VIPS_WARNING is defined, suppress all warning messages from vips by
installing a null log handler.
Libraries should not call g_log_set_handler(), it is supposed to be for
the application layer, but this can be awkward to set up if you are using
libvips from something like Ruby.
This env var hack is a workaround.

the old 'disc' flag to open defaulted TRUE and disabled read via disc if you
set it FALSE, which was very confusing
replace it with a flag called 'memory' which defaults FALSE and forces
read via memory if set TRUE
'disc' is still there and still works, it's just tagged as deprecated
see https://github.com/jcupitt/libvips/issues/677
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!

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
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
