this works:

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.

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!

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.

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.
