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.

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.

John Cupitt
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 
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.

bd8a6980f5 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

ac4897abee Fix up vips_text() 
Fixes two issues:

1. vips_text() in autofit mode could set the wrong DPI, since it set the
DPI in its own copy of the variable, but did not do a final update on
the DPI setting that FT uses for rendering.

2. vips_text() in autofit mode allocated a new context each time, rather
than reusing the context for that call. This caused a small memory leak.
