Previously, the unpremultiplied values from the GdkRGBA were taken. Now
we premultiply the color values as specified by the CSS specs.
This is only relevant when transitioning with translucent colors.
An example is the halfway transition between transparent (0, 0, 0, 0)
and white (1, 1, 1, 1). Previously, all 4 values where transitioned
separately and the result was semi-transparent gray (0.5, 0.5, 0.5,
0.5).
By depending on the alpha value, the result is now semi-transparent
white (1, 1, 1, 0.5) which is what one would naively expect.
New reftest: color-transition
On some slower machines (e.g. an ARM OBS builder), this test is failing
with a race condition where we're trying to fetch the style before it's
applied.

gtk-reftest already had an --output=DIR option to tell it where
to save all the resulting images. Now you can combine this with
the --compare-with=DIR option in a second run to make gtk-reftest
compare the .out.png files from the first run with the .out.png
files of the current run, instead of producing .ref.png files.
The intended use for this is to verify that changes do not affect
the generated output.
Sometimes path nodes can survive longer than the style context that
created them. Don't crash in those cases.
Fixes startup of mutter.
Testcase included.

We are testing -gtk-icon-style and assume the theme doesn't touch it.
But HighContrast forces symbolic icons. And that breaks the reference
images.
So explicitly set "requested" for everything.
It seems to be buggy in ways that make the test fail
with a critical when the test bus is brought down.
At the same time, drop manual settings of environment
variables that we can set globally.
gtk_tree_selection_real_modify_range() has a g_return_if_fail() if the
start or end paths passed to it do not correspond to real tree nodes.
However, GtkTreePaths inherently do not have to be valid, so it should
be acceptable to call gtk_tree_selection_select_range() with
non-existent paths. Replace the g_return_if_fail() by a silent return,
and add a unit test.

Don't try to paint onto an error surface. This happens for example when
gdk_cairo_set_source_pixbuf() is called with a pixbuf that is too big
for Cairo to handle.

GPUs generally have problems when you create a 35000px wide surface.
Luckily X catches this and sends a BadAlloc. Which GTK immediately
abort()s on.
Testcase included.

If a side of the box is 0px wide, make the corners owned by the adjacent
sides. This avoids spilling over of unwanted colors from the 0-width
side into the corner.
New test for this case is included.
After 3a337156d1 style lookups still used
the parent context's style as the parent style, even though after a
gtk_style_context_save() the root style of the style context is the
proper parent.
Testcase attached.
1) Use font-size instead of color
This makes it easier to compare reference and test because the values
don't change.
2) Actually sort the reference properly
This unbreaks the test.
