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

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

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

stencil position elsewhere. The right way to do centre convention is to offset
the whole input by 0.5 pixels.

smarter conversion of float masks to int
...
we were just rint()ing masks going from float -> int, but this could
give bad results in some cases, with output images becoming darker
or lighter, as individual elemets moved up or down
now we adjust the output scale to try to keep the overall brightness
the same, if we can
