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

dzsave with deepzoom layout and fs container writes a temp dir called
dzsave-temp-324857 or similar, and makes sure that this directory does
not exist

after write, the foo_files and foo.dzi files are picked out to the
current dir and the temp removed

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.

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.
