e8a78916a3 add support for palette mono images 
search the colormap for R==G==B and output mono in this case

there is a tiff extension for INDEXED images, but no one seems to use it

f13bf34ce3 add n-bit palette tiff read 
The tiff reader can do 1, 2, 4, 8 bits per sample palette read.
Greyscale palette images always come out as colour, I'm not sure how to
fix this. Perhaps I have to search the palette and see if r==g==b?

16b032f8c1 more hackery 
getting closer, stuck on vips image byte-swap logic now, probably need a
im_file2vips() type function

a7d2288bad im_jpeg2vips() ignores weird APP1 chunks 
Some JPEGs seem to have multiple APP1 chunks. There should only be one,
and it should only contain EXIF data (I think), but some seem to have
many.

This was causing problems: the loader was trying to read exif
from all chunks, and a second chunk with invalid data was zapping the
stored exif meta tag. As a result, things like

  vips im_copy a.jpg b.jpg

would appear to lose EXIF info if a.jpg had spurious APP1.

729b680841 set MAP_NOCACHE if we can 
Set the MAP_NOCACHE flags in mmap() if we can. On OS X this stops the
mad super-aggressive disc caching and produces a huge improveemnt in
performance.

444887e57f more informative progress messages 
--vips-progress now tells you nthreads, tile size and nlines. For
example:

$ vips --vips-progress im_shrink big.v x.v 8 8
vips x.v: 2 threads, 2858 x 1 tiles, groups of 4 scanlines
vips x.v: done in 43s

390fd643a3 move im_dif_std() to almostdeprecated 
im_dif_std() is another ancient function which I don't want to update.
You can now make this function with a simple combination of other vips
operations.

This patch includes gtk-doc for im_benchamrk.c

233cbf1f15 get all fopen()s going through util.c

route all fopen() though these two functions.

663c3c15fd fits reader is lazy 
The fits reader is now lazy, and reads out whole tiles when it can.
Previously it read a scanline at a time, and used WIO.

We read in planes and combine with a set of im_bandjoin().

Use an im_flipver() at the end to get rows in the right order.
