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

2ea5c5f7e5 make python bandrank() work like bandjoin() 
we had a custom wrapper for bandjoin(), but bandrank(), a function with
an almost identical interface, did not ... this was confusing

bandrank() now has a custom wrapper too ... this breaks API
unfortunately, but hopefully very few people were using this thing and
it's better to make this change as soon as possible

25c3c49d1c better handling of cast+shift for non-int formats 
before, im.cast(uchar, shift = true) where im was float and tagged as
rgb16 would not shift the image, since it's unclear how much to shift a float
type by

now we do two casts: first, we guess the numeric range from the
interpretation, so rgb16 would be ushort, so we cast float->ushort;
second, we cast to the target type and do the shift on the way

see https://github.com/jcupitt/libvips/issues/397

c1f1a7c1b3 improve sharpen for screen work 
it was a bit granular (since it was designed for offset work), make sharpen
easier to adjust for smaller effects

- new 'sigma' parameter
- greater parameter range
- more self-tests
