This adds an inhibit api that code from the reftest module
can use to delay the taking of the snapshot. Also refactor
the code in gtk-reftest to use the inhibit mechanism for
its own delaying of the snapshot until after the first
expose.
This reftest makes use of the new feature to add signal handlers.
It adds a libreftest.so module containing all the code for the reftests.
When adding a test named reftest.ui, please keep code contained in a
source file names reftest.c and add that file to Makefile.am.

When connecting signal names, gtk-reftest now allows you to use a colon
in the signal handler name like so:
module:function_name
where module is a module loaded from the same directory (or the .libs
subdirectory for compatibility with uninstalled libtool) as the running
test and the function is resolved in that module. Of course, normal
function names work as before.
This test is a bit brittle because it doesn't properly rely on CSS
properties but needs to use widget style properties to turn of extra
sizing from widgets.
It might break in the future when porting widgets to draw properly.
Quoting the spec:
If the cascaded value of a property is the unset keyword,
then if it is an inherited property, this is treated as
inherit, and if it is not, this is treated as initial.
Spec in question:
http://dev.w3.org/csswg/css-cascade/
Also use unset in the reset-to-defaults.css we use to reset css in
reftests.
The color chooser test is constantly running into the
problem that the custom color setting is not empty.
Avoid that by using the memory settings backend.
When downscaling images, Cairo apparently uses algorithms different
enough to make this test trip over. So add the downscaled image as the
reference instead of downscaling the previous reference image.
Fixes the border-image reftest. For real now.
The new downscaling code in Cairo doesn't allow this test, so we remove
the CSS that made the border downscaled.
So the test does test less now, but it still tests the repeat modes of
border images.
nth-child() is 1-indexed, not 0-indexed.
It doesn't matter for this test really, but better do it right to not confuse
poor developers who wonder why the first image is highlighted when nth-child(0)
clearly states "none".
The reftest is a bit flaky because it compares cell renderers with
GtkImage and therefor an icon view with a GtkBox, but it's the best I
can come up with.
