c5e675f7db fix --vips-cache-max etc. 
--vips-cache-max, --vips-cache-max-memory and --vips-cache-max-files were not
working and probably hadn't been for a while

vipsthumbnail.c turns off the operation cache, it's not useful for
the same operation repeated across many files

2be0b97dce switch to g_warning()_/g_info() 
we had vips_warn() and vips_info(), but they are a bit crappy ... switch
to g_warning() and g_info() instead

we were not updating argc in vips.c after all calls to
g_option_context_parse_strv() on Windows, leading to a crash in some cases

54d8e4808f restore bandfmt after unpremultiply in thumbnail 
vips_unpremultiply() always outputs float. If you save the output of
vipsthumbnail to a format that supports float files, like tiff, it won't
ever get cast back to the source format.

Example:

	$ vipsheader Opera-icon-high-res.png
	Opera-icon-high-res.png: 3056x3325 uchar, 4 bands, srgb, pngload
	$ vipsthumbnail Opera-icon-high-res.png -o x.tif
	$ vipsheader x.tif
	x.tif: 117x128 float, 4 bands, scrgb, tiffload

This change makes it note and restore BandFmt aropund pre/unpremultiply.

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

ad7ddc4f24 more vips_resize() tuning 
now we have better tuning for the anti-alias blur, we can increase the
amount we shrink by and reduce the amount we affine by

this gives a noticable speedup

8506ff13a6 try to improve vips_resize() quality 
small improvements to vips_resize() quality:

* turn down the anti-alias filter a little so we don't smudge out texture
* don't do the final sharpening pass if we skipped the anti-alias filter
* fix a >/>= mixup which meant we didn't sharpen for small resizes
