- added vips_image_write(), old one becomes vips_image_write_to_file()
- jpeg read/write copies over XMP data
- handle offset correctly in separable convolutions (thanks Nicolas)
- macros for class arg boilerplate
- class arg order set by new 'priority' param
- VipsExtend enum added
12/9/11 started 7.26.4
- fallback vips_init()

- embed args are in the wrong order
$ vips embed
vips_embed_class_init
VipsEmbed (embed), embed an image in a larger image
embed input type x y width height out
where:
input :: VipsImage (input)
type :: gint (input)
x :: gint (input)
y :: gint (input)
width :: gint (input)
height :: gint (input)
out :: VipsImage (output)
how can we fix this?
need to give an extra arg to vips_object_class_install_argument() to
specify 'argument priority' ... show args in priority order
- try some macros for arg specification
pspec = g_param_spec_int( "y", "Y",
_( "Top edge of input in output" ),
0, 1000000, 0,
G_PARAM_READWRITE );
g_object_class_install_property( gobject_class, PROP_Y, pspec );
vips_object_class_install_argument( vobject_class, pspec,
VIPS_ARGUMENT_REQUIRED_INPUT,
G_STRUCT_OFFSET( VipsEmbed, y ) );
could become
VIPS_ARG_INT( class, "y", "Y",
_( "Top edge of input in output" ),
0, 1000000, 0,
VIPS_ARGUMENT_REQUIRED_INPUT,
G_STRUCT_OFFSET( VipsEmbed, y ) );
could get rid of PROP_ enums as well
doing binary.c next
- make 'type' field to embed an enum?
- vips_object_set_argument_from_string() needs more arg types
must be some way to make this more automatic

* 15/4/04
* - added replicate and mirror modes
* 4/3/05
* - added solid white mode
* 4/1/07
* - degenerate to im_copy() for 0/0/w/h
* 1/8/07
* - more general ... x and y can be negative
* 24/3/09
* - added IM_CODING_RAD support
* 5/11/09
* - gtkdoc
