experiment with a different early-close strategy
...
We close loaders early in order to save file handles, and on Windows to
make sure that files can be deleted as soon as possible.
Currently loaders do this by watching the Y coordinate of requests and
freeing the fd when the final line of the file is fetched. This is messy
and does not always work, since there are cases when the final line is
not fetched.
Instead, this patch gets loaders to listen for "minimise" on their
output and close on that. This signal is emitted on all upstream images
whenever a threadpool finishes a scan of an image and is usually used to
trim caches after computation.

don't attempt to save large XMP to JPG
...
jpeg_write_marker() with some libjpeg versions will throw a fatal
error with large chunks.
To write >64kb XMP it you need to parse the whole XMP object,
pull out the most important fields, code just them into the main
XMP block, then write any remaining XMP objects into a set of
extended XMP markers.
http://wwwimages.adobe.com/content/dam/Adobe/en/devnet/xmp/pdfs/XMPSpecificationPart3.pdf
Instead, just warn and skip large XMP blocks.

istiff tests first dir rather than magic number

We were testing for TIFF by checking the magic number at the head of the
file. However, formats like ARW are TIFF-like without being TIFF, and
will not load with tiffload.
Instead, try reading the whole of the first directory. This is enough to
stop tiffload trying to load files where it will simply fail
immediately, and make libvips fall back to eg. imagemagick.

Fix up vips_text()
...
Fixes two issues:
1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.
2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.

strict round down on jpeg shrink

libjpeg rounds up on shrink-on-load. In some cases this can leave a dark
line along the right and bottom edge, since it only contains (for

output.

create funcs always make MULTIBAND
...
Before, they could make B_W for one-band output. This caused problems
with (for example) two black image bandjoined: the second band then
looked like an alpha to hasalpha() and enabled premultiply/unpremultiply
for operations like affine.
Now, it's always MULTIBAND. This is the generic multiband image type, so
you don't get any unexpected alpha handling.

The result of hasalpha is used to turn on things like

icc_import attaches the input profile if used
...
icc_import can take a fallback input profile in case the embedded one is
broken or missing. If we use the fallback profile, this change attaches
it to the output image.
This means that icc_import will always output an image with the icc
profile that was used to import it. This helps to make the behaviour of
`thumbnail` more consistent.

improve rounding in convi intize
...
We were rounding up with ceil() when intize-ing convolution masks.
However, the vector path has a true range of (1.0, -1.0], so a mask with
1.0 as the max (for example) was actually triggering the overflow detector
and falling back to the C path.
Round up with ceil(x + 1) instead, so 1.0 (for example) will be mapped
to 0.5 and won't overflow.

hide warnings if VIPS_WARNING is defined

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.

upsize with something other than nearest
...
vips_resize() uses to just use nearest when upsizing, following standard
practice in repro. This is often unfortunate for image processing, where
small nearest upsizes will produce obvious aliasing.
It now picks a VipsInterpolate which corresponds (roughly) to the
selected VipsKernel and uses that with affine for any upsizing.

better vips_resize() for cubic/linear/nearest
...
vips_resize() used to do most of a downsize with vips_shrink() and the
final 200 - 300% with vips_reduce(). This was correct for lanczos2/3,
but not right for linear/cubic, which need more shrink and less
reduce to avoid aliasing.
This patch makes vips_resize() leave the final 100 - 200% to
vips_reduce() for linear/cubic, and leave everything to reduce for
nearest.

vips_image_write() only refs input when it has to
...
when you write to a non-partial image, you create a sink ... so
vips_image_write() only needs to ref the input when writing to partials
this change makes it much easier to (for example) combine many images in
bounded space, see for example:

free pixel buffers on image close
...
We were freeing pixel buffers on thread exit. This was convenient, but
meant that main thread buffers were not freed until program exit. As a
result, long-running programs which created main thread buffers would
slowly fill the operation cache with useless junk, forcing everything else out.
This change also frees pixel buffers on image close. This makes the
cache work much better in long-running programs, and can substantially
reduce memory use.

free main-thread pixel buffers
...
threads keep pixel buffers in thread-private storage, and free these
buffers on thread exit ... this means buffers created by the main thread will
only be freed on program exit!
if your program creates any main-thread buffers, these buffers will
eventually fill the operation cache and force everything else out,
making the cache useless
this patch explicitly frees main-thread pixel buffers on image close
