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

output image back into libvips again

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

version bump

John Cupitt 36e0b60ffa put the resize cache back again

John Cupitt 3c98ba78a0 small experiment 2016-03-22 14:19:32 +00:00
John Cupitt 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
