You must now include vips7 support explicitly with
#include <vips/vips7compat.h>
in your code just after including `vips.h`.
The old vips7 names, such as `Rect`, were starting to cause problems
with other packages like opencv.
icc_transform does a better job of guessing the colourspace of an image -- if
the colourspace has not been set (generic multiband), it'll look at the
image bands instead and guess from that

Both vips_cache_drop_all and vips_cache_print acquire vips_cache_lock
on entry, but vips_cache_drop_all calls vips_cache_print internally if
vips__cache_dump is true, leading to a deadlock situation.
This commit solves the issue using one further level of indirection
and a new vips_cache_print_nolock function.
The value is derived by oring all the filter flags:
0x08 | 0x10 | 0x20 | 0x40 | 0x80 == 0xf8
The value was also checked against PNG_ALL_FILTERS in png.h.
- make access() fail only if we are certain the file does not exist
- remove the g_mkstemp() from vips__temp_name()
should help selinux

Some magick coders (eg. ICO) don't sniff the filetype from the data, so
when you try to load from a string, imagemagick is unable to pick the
right decode path.
Add a @format option so callers can hint the filetype.

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
example) 1/4 of a pixel of data.
This change adds a crop after jpeg load so that only complete pixels are
output.

If O_TNMPFILE is available, use it. This is a linux extension that
creates an unlinked file, so it'll be closed by the system when the last
associated fd is closed.

TODO
- more code sharing with pdfload.c, eg. vips_foreign_load_pdf_is_a_buffer()
and get_flags etc.
- could share the page layout code too
- make pdf.c with base stuff in?
- what about filename encodings
- test transparency
- new_from_buffer needs doing
