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

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:
