90536d2268 try openslide before jpeg 
MRXS images are also JPEG images, so we need to have openslide before
libjpeg in the file test order.

618af96723 vips_system() out-format can take options 
you can now put options like [scale=2] at the end of out_format ...
these are stripped before running the command, but use to load the
output image back into libvips again

72ea91fecc fix nohalo, vsqbs interpolators 
we were getting occasional memory access problems in nohalo and vsqbs
interpolators ... the previous fix was not enough

e8b5cb6c23 add VIPS_COUNT_PIXELS, overcomputation tracking 
added VIPS_COUNT_PIXELS(), use like this:

	static int vips_shrinkh_gen( VipsRegion *or, ... )
	{
        	VIPS_COUNT_PIXELS( or, "vips_shrinkh_gen" );
	}

and on image close, if more than 100% of the pixels have been
calculated, you get a warning

only if you enable debugging, since this hurts perf slightly
