baf78fc04a oops, fix base64 encode/decode padding
we were adding up to two bytes of null to the end of base64-encoded
binary data due to a signed/unsigned mixup

add a test for this, plus a test for vips file format

78acd9b7a0 use a better name for the dzsave temp dir
see https://github.com/jcupitt/libvips/issues/242

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.

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.
