John Cupitt 764ce559f8 better benchmark prog 
the benchmark program (benchmark/benchmarkn.sh) runs each test three
times and just reports the fastest run

it also detects the number of CPUs you have and automatically loops the
right number of times

additionally, tiles now default to 512x512, so it explicitly sets tiles
back to 64x64 to make comparisons with earlier versions easier

VIPS SMP benchmark
------------------

This is adapted from the system used to generate images for POD:

  http://cima.ng-london.org.uk/~john/POD

Images from a 10k by 10k studio digital camera are colour processed, resized,
cropped and sharpened. 

This thing was originally processing images off a remote server over a 100mbit
network. No attempt was made to make it quick (there was no point): you 
could make it a lot faster very easily.

See

 http://www.vips.ecs.soton.ac.uk/index.php?title=Benchmarks

for results.
