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

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
