66373e9b41 remove exception specs from vips8 C++ interface 
We had exception specs on the C++ interface, but C++11 does not support
them and some compilers have never honoured them. Remove all specs.

e81900b187 bandjoin is just an instance function 
we had both a class member bandjoin, and an instance member

Vips.Image.bandjoin([i1, i2, i3..])
i1.ibandjoin([i2, i3..])

this was confusing and annoying ... get rid of the class one and just
use bandjoin everywhere, so this is now the way to do it:

i1.bandjoin([i2, i3..])

6573af3c2a always strip dzsave tile metadata 
dzsave now uses :strip => true for all tiles. There's no point adding
all the metadata to every tile, so hopefully this won't break anything.

8506ff13a6 try to improve vips_resize() quality 
small improvements to vips_resize() quality:

* turn down the anti-alias filter a little so we don't smudge out texture
* don't do the final sharpening pass if we skipped the anti-alias filter
* fix a >/>= mixup which meant we didn't sharpen for small resizes

3b32200cc1 sizealike() and friends elide completely 
sizealike() / formatalike() and bandsalike() used to just vips_copy() if
the image didn't need any changes ... this was fast, but left a
vips_copy_gen() in the pipeline, wasting a lot of space on the C stack
during recursion.

They now vanish completely if the image is already in the right format.
Since we call them before most image processing operations, and
often all three of them, this saves a lot of C stack, more than x2 even
in simple cases.

There might also be a measureable CPU saving if the operations are very
simple (eg. insert).

66fe338d36 better alpha handling for tiff save 
the tiff saver was writing all five-band images as CMYKA, even if they
were tagged as srgb ... it now follows the interpretation tag and will
write many alpha channels instead

64d081e726 return default value for unset props 
we used to issue a warning and return early, but this can leave garbage
in the *value pointer, I think

ruby gobject-introspection will walk object props during GC and can see
state inbetween init and build when not all objects have been given a
value ... we don't want these warnings

fbe321eebf change exif names argh 
change exif names again: we were storing under @title, but that's both

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.

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.

004c98f296 pngsave interlaced makes a copy of the image 
interlaced png is hard to write: you have to make seven passes over the
image to make the whole file. It advertises itself as sequential, it
needs to only ake a single pass. Therefore, it must take a copy in
memory of the image to write.
