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.

disable Orc if CET is on

If we are building with -fcf-protection (run-time checking of
indirect jumps) then Orc won't work. Make sure it's off.
Orc may support -fcf-protection in the future, but does not in June 2019.

better behaviour for vips_region_fetch()

cases we could return many more pixels than expected

much faster ismagick
...
We used to Ping files to see if IM would load them, but this can be
extremely slow for file formats like ARW.
Instead, use GetImageMagick() ... it just checks the magic number.

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.

more consistent behaviour for multi-page load
...
Some loaders were setting page-height even when the user was loading a
single page triggering unexpected multi-page behaviour from later
savers.
New rule: only set page-height when loading more than one page.
