2c654060f9 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.

8cf6a9f9ca 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.

oss-fuzz. By default, the fuzzers are linked against an standalone runner to

We were setting TIFFTAG_JPEGCOLORMODE == JPEGCOLORMODE_RGB for *all*

55e49831b8 add "unlimited" to svgload 
By default librsvg blocks SVGs > 10MB for security. This patch adds an
"unlimited" flag to remove this check.

We have to switch to using gio to get the librsvg API for this This
needs testing on the platforms we support.

We'll also need to bump the min version of librsvg we require in
configure.ac.

80648c2d2f text autofit could sometimes underfit 
The autofit loop would terminate if either width or height fitted exactly,
but this could happen very early by chance. This patch makes it keep
looping until it finds a dpi which just fits.

d1094847a3 remove no-alpha webp support 
We used to try to spot webp images with no alpha and load them as plain
RGB, but it turns out this is difficult to do reliably, especially
for animated images.

This patch simply removes support, so all webp images now load as RGBA.

bb75535151 much faster ismagick

John Cupitt
eb6c803481 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.
