calculates image entropy from a histogram

fbe321eebf change exif names argh 
change exif names again: we were storing under @title, but that's both
subject to i18n, and unlookupable in libexif

we now use @name, which is not subject to i18n and can be searched for
... this will break most code which expects certain exif tag names

also, when we update exif, allow any tag, not just updates to existing
tags, see:

366e7e3a5e add gobject to Requires: line 
vips C and C++ programs can link directly against things in gobject
without appearing to, for example:

	a = VIPS_OBJECT( b );

the macro will expand to include a g_type_check_instance_is_a(). So we
have to have gobject-2.0 in the link line of things like:

	g++ -g -Wall hello8.cc `pkg-config vips-cpp --cflags --libs`

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.
