- add "mode" param to vips_draw_image()
- add vips_hough_circle()
- reduce default cache size to 1,000 operations
- added "postbuild" signal
- vips_system() now supports many input images and you can change image
argument order
6/3/14 started 7.38.6
- grey ramp minimum was wrong

- try:
$ vips system "vips add %s %s %s" --in "k2.jpg k4.jpg" \
--out-format "%s.tif" --out x.v --log
memory: high-water mark 9.37 MB
""
memory: high-water mark 27.89 MB
$
but x.v does not appear
- can we use postbuild elsewhere? look at use of "preclose" / "written", etc.
- why is cache in nip2 so slow? its awful
investigate again
is it using vips_sinkscreen()? should it use tilecache?
- test draw_mask on labq images
