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

much better handling of arrayimage cli args
...
we were not setting the access hint on arrayimage args, so
arrayjoin "$(echo *.jpg)" x.tif[bigtiff] --across 10
would open all the jpg images to memory, usually, in random mode
now arrayimage args see the operation's access hint (seq in this case),
for much better behaviour
also, we allow any whitespace as an arg separator in arrayimage from
string

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.

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.
