26100041e7 fewer warnings on tiffload 
We were setting TIFFTAG_JPEGCOLORMODE == JPEGCOLORMODE_RGB for *all*
images, but libtiff warns if you use it on an image which is not
jpg-compressed.

Only set it for jpg-compressed images.

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.

75e69cc1e5 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.

bb75535151 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.

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.
