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.

a1ed6c7f6c improve GIF edarly close again 
We were trying to keep the FILE open for gifload between header and
load, but this meant some corrupt GIFs could keep the file open longer
than they should.

Instead, make close into a vfunc and always close between header and
load.

46212e92b1 fix default sharpen 
sharpen with sigma 0.5 was doing nothing, since the new int precision
rules meant that we generated a point-point convolution.

This patch increases the int precision for sharpen, so we now work with
sigma down to 0.5.

Also: restore input colourspace. Previously, the output image was always
LabS (the computation space for sharpen). Now, it transforms back to the
input space. This is more in line with how other operators work.

Thanks 2h4dl for pointing this out.
