fcc33020bd better exif handling 
- track ifd numbers for each item of exif
- be more careful about which ones we update
- don't update xres/yres in vips_shrink()

efcc53859a capture tiff warnings during startup 
We were not capturing warnings from libtiff until we used libtiff
ourselves. Other libraries whcih we call, such as ImageMagick, could use
libtiff and generate an uncaptured warning.

On Windows these warnings each produced a popup.

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

flags for now are "nocache" (replacing the old nocache system) and "seqential"

if vips_object_set_argument_from_string() from string sees "seq" flag on the
object for which it is setting the arg, it enables sequential mode

all operations which can run sequentially have been tagged

the operation printer knows about flags and can display them

0290eb009d more accurate progress reporting 
computation progress used to be done incrementally based on the number
of tiles allocated. This did not take account of half tiles at image
edges, so you could sometimes see "110% complete"

it's now calculated based on the absolute number of pixels processed, so
it should always report 100% at the end.

4b2c8587b2 vips_malloc() size tracking 
vips_malloc() now tracks allocation size and can report total mem use.
It seems to trigger quite a few nip2 bugs though, I guess we are
g_free()ing the result in places (or vice versa).

764ce559f8 better benchmark prog

back to 64x64 to make comparisons with earlier versions easier
