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

easier to adjust for smaller effects

18baf40b1a fix mapim typo 
oops! typo ... also an off-by-one issue for larger stencils

more error checking in interpolators

fix rounding in nohalo/lbb ... they were rounding to nearest in the
interpolator, rather than using floor. This broke assumptions about
stencil position elsewhere. The right way to do centre convention is to offset
the whole input by 0.5 pixels.

small improvements to vips_resize() quality:

* turn down the anti-alias filter a little so we don't smudge out texture
* don't do the final sharpening pass if we skipped the anti-alias filter
* fix a >/>= mixup which meant we didn't sharpen for small resizes

de65da85b9 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

it was getting too hard to support :( automake now generates libtool
lines before configure runs, so it can't know we don't want a C++ link

6e2135d8b5 mask builders take prec, not integer 
vips_gaussmat() and vips_logmat() used to default to float, but
vips_conv() defaulted to int ... so this failed:

	vips gaussmat m.v 2 0.1 --separable
	vips convsep k2.jpg x.jpg m.v

since we were using a small float mask with an integer convolution

This change makes everything int by default, with gaussmat having a new
param called --precision whose arg can be int or float.

The old @integer param is deprecated.

384a5e05dc change parameters of vips_gaussblur() 
sorry :-(

The old param (passing sigma*2 as an int) were just too confusing
coming from other packages. This new behaviour matches ImageMagick, and
almost everyone else in the world.

A new optional param lets you set the minimum amplitude as well.
