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.

e9ce212b62 make out of order read a fatal error 
For png and jpg, out of order must always be a fatal error, since you
can't read from a specific y position.

This was a g_assert() before which meant that this test was missing from
production builds. It's now always a fatal error.

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.

594af28c8e remove support for seq mode read for extract etc. 
see comment in sequential

We used to not stall if the read position was zero, ie. if the first
request was for a line some way down the image, and assume this was
extract or somesuch. But this could sometimes break on busy, many-core
systems.

Think of a better way to support eg.  extract safely in sequential mode.

which iipsrv can handle.

Using this flag makes files 2x to 3x larger with no quality improvement,
so it is tagged as deprecated to keep it hidden.

bbd5cbfb44 add vips_thread_shutdown() 
You now need to call vips_thread_shutdown() from all threads you create
yourself just before they exit. This gives vips a chance to free any
thread-private memory and to write out profiling data. libvips will
complain noisily if you fail to do this. You can harmlessly call
vips_thread_shutdown() more than once if you wish.

libvips will call vips_thread_shutdown for you automatically for the main
thread (the one that calls vips_shutdown()) and for threads it creates
directly itself.
