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.

f45f0ecef4 limit resize if shrink would drop axis <1px 
vips_resize() will break the aspect ratio and limit resize on an axis if
it would result in an image of less than 1px on that axis

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.
