The --rotate flag no longer did anything, so add a new --no-rotate flag
connected to the new no-rotate property. --rotate is still there, but
hidden and does nothing.
-o was much easier to remember than -f, so flip back to -o. -f still
works, but is a hidden synonym.
--iprofile, --eprofile were hard to remember. Add --import-profile and
--export-profile synonyms. iprofile / eprofile are still there and still
work, but are hidden.
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.
"intent" lets you set the rendering intent for any ICC conversions --
the default is the (more correct) relative, but "perceptual" can look
better

can't use GRegexp if we need to support centos5 ... vipsthumbnail was
using it to parse geometry strings
new geo parser, plus some tests
see https://github.com/jcupitt/libvips/issues/622
--vips-cache-max, --vips-cache-max-memory and --vips-cache-max-files were not
working and probably hadn't been for a while
vipsthumbnail.c turns off the operation cache, it's not useful for
the same operation repeated across many files
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.
Example:
$ vipsheader Opera-icon-high-res.png
Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
$ vipsthumbnail Opera-icon-high-res.png -o x.tif
$ vipsheader x.tif
x.tif: 117x128 float, 4 bands, scrgb, tiffload
This change makes it note and restore BandFmt aropund pre/unpremultiply.

jpeg write is more careful about removing exif tags that have been
removed from the image metadata
it failed previously if there were multiple Orientation tags
