b981911f67 remove redefinition of typedefs 
We had this in a couple of places:

	typedef struct _A A;
	typedef struct _A A;

Some old gccs (eg. centos6) throw errors for this.

e4d38d1d3e clip out of bounds GIF images against the canvas 
Some malformed GIFs have images which lie outside or partly outside the canvas.
With this patch, these frames are clipped and rendered.

Previously, these GIFs were rejected.

1e015654c3 deprecate heifload autorotate 
heifload autorotate is now always on, and we always delete EXIF
orientation tags. If a HEIC image fails to rotate upright, at least it's
someone else's fault.

- deprecate vips_autorot_get_angle() since orientation is no longer a
simple rotate
- add vips_image_get_orientation() and vips_image_get_orientation_swap()
- revise tiff and jpeg loader autorotate to just call vips_autorot(),
but only if necessary
- revise thumbnail autorotate too

ba0dea001d sort out premultiply rules for upsizing 
vips_resize() uses vips_affine() for upsizing and vips_reduce() for
downsizing. Affine automaticaly does a vips_premultiply() for images
with an alpha channel, but reduce does not. This meant that we could
sometimes premultiply twice.

This patch adds a "premultiplied" flag for affine which turns automatic
premultiuplication off, vips_resize() uses this to block affine's auto
premul feature, and the resize docs are clarified to stress that the
operation does not do premultiplication for you.

efd62acccd better iiif tile naming 
We were clipping edge tiles against the size of the scaled up layer.
Instead, clip against the size of the top level image.

6f0548dc5c thumbnail could fail on HEIC in some modes 
in locked UP or DOWN mode, vips_thumbnail() could incorrectly select the
thumbnail from a HEIC image even when it was not large enough to
generate the output image.
