5916e25c31 rename python bandjoin as ibandjoin 
oh argh class and instance methods are in the same namespace, so we have
to rename the instance one as ibandjoin

also, start adding a test for arrayjoin

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.

8506ff13a6 try to improve vips_resize() quality 
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
