Check for image alpha and enable it. There seem to be some
non-transparent tiles, curiously.

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.

574be4380e revert sharpen restoring the input colourspace 
icc_export can make _RGB images, so the input can be outside the set of
supported colourspace transforms.

See 46212e92b1 (r34904985)

bump version too.

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.
