b3a8ff3378 linecache was oversized 
the linecache resizer forgot to take the strip height into account when
growing, causing mem use to be higher than necessary

7a0441d455 delay rather than stall ahead threads 
avoid deadlocks by only slowing down threads which run ahead of the read
point

4ef825014d extract is sequential again 
a hack in seq.c will skip ahead if the very first read is not at line 0

b183d32b15 use a hash table for tilecache

dynamically with request size

45e3c0bd39 fix some warnings from jpeg write 
jpeg write with a non-jpeg source could produce some warnings as it
tried to update exif that wasn't there

1abac4018a better enum arg error message 
you now get something like:

$ vips tiffsave k2.jpg x.tif --compression poop
tiffsave: enum 'VipsForeignTiffCompression' has no member 'poop', should be one of: none, jpeg, deflate, packbits, ccittfax4, lzw

463058c149 note and use res unit on jpg load/save 
previously, jpeg save always used pixels/inch and jpeg load converted to
vips pixels/mm

now on jpg load the image's res unit is recorded in
VIPS_META_RESOLUTION_UNIT, and on jpg save the res unit is set from
VIPS_META_RESOLUTION_UNIT (or defaults to inches).

you can now copy a cm-preferring tiff to a jpg and the unit is preserved

8214d15982 more improvements to dzsave 
now writes x_files and x.dzi, as per spec (thanks Benjamin)

deprecate tile_width and tile_height, just have tile_size now

0c35f461dc add "deprecated" flag to vips arguments 
deprecated arguments still work, but are not shown in help, nor are they
checked for "have-been-set"

you can tag required and optional args as deprecated ... obviously if
you deprecate a required argument you must replace it with a new
argument or scripts will break

a9c7a36670 be more cautious enabling tiff ycbcr 
we were turning on ycbcr for all jpeg tiffs and relying on the jpeg
compressor to only use it when possible ... now just turn on ycbcr for
8-bit RGB images

dab22df75b fixes to deep zoom write 
- shrink down to a 1x1 pixel tile, even for very long and thin images
- round image size up on shrink
- write a .dzi file with the pyramid params
- default tile size and overlap now matches the openslide writer

thanks to Benjamin Gilbert for pointing out the errors

5778dfac1a remove the version numbers from the .pc files 
we used to have minor version numbers in the pkg-confiog files, eg:

pkg-config vips-7.28 --cflags

The idea was to make working with multiple installed versions (something
I do a lot at least) easier. But it was also annoying and made upgrading
harder for downstream packages. And the benefits were very marginal.
