c107066c4e Add webpsave near_lossless support, fix Q range
The near_lossless option allows to enable preprocessing for the lossless
mode. This is a boolean instead of an int, because the amount of
preprocessing is controlled using the Q factor parameter which is
otherwise unused in lossless mode. This allows to re-use the quality
setting in existing tools.

58a2616f77 New webpsave option smart_subsample
This enables a high quality RGB to YUV converter in libwebp which
greatly improves the quality of fine details by reducing color bleeding
caused by the 4:2:0 chroma subsampling. This is slower and causes
slightly larger files. See WebPPictureSmartARGBToYUVA in libwebp.

23eaf93867 fix build with graphicsmagick
GM is still using the old page interface of subimage/subrange, IM has
deprecated that in favour of scene/number_scenes

we were accidentally just supporting the new IM system ... this change
adds support for GM as well, plus a configure test to pick one

2c646a02e4 better jpeg autorot
jpeg write is more careful about removing exif tags that have been
removed from the image metadata

it failed previously if there were multiple Orientation tags

Photoshop uses 0 - 1 and no gamma for float RGB, so we tag float /
complex RGB tiffs as scRGB

MRXS images are also JPEG images, so we need to have openslide before
libjpeg in the file test order.
