712157cd16 better support for TIFFs with many alphas 
The premultiplied alpha can be in any position, and it checks if there

71b557cfc1 remove "minimise" handler from tiffload 
We need to be able to disconnect the underlying fd and we can't do that
without making our own input handler for files. Implement this when we add
input objects.

1ef1b2d987 much faster handling of missing heif thumbnails 
Fetching the thumbnail from a heif image without a thumbnail used to
reselect the image for each scanline, which was horribly slow.

Thanks Kleis!

a92f0ed504 smarter heif thumbnail selection in thumbnail 
We were checking for thumbnail width and height > target width and
height, but of course we can have one of target width or height very
large if we are leaving that axis to float in size.

Instead, calculate a shrink from the heif thumbnail size and see if that is
>= 1.0, ie. we can generate output without upsizing.

0323b77666 pdfload reopens after minimise if necessary 
We were using "minimise" to close pdf input early, but this will break
programs which make several output images from one sequential input
image. For example, loading all pages of a PDF as a toilet-roll image,
then saving pages as a set of PNGs.

This patch adds vfuncs for open and close, and makes _generate reopen
the input if necessary.

We will need similar patches for pdfiumload, gifload, gifnsload,
tiffload etc.
