1116914ea0 css: Move scale to GtkStyleProviderPrivate
This way, we can remove it as a separate argument from
gtk_css_value_compute() and allow computation to only depend on one
thing: the style provider.

e697213b35 render: Remove spinner special-cases
The spinner is a regular builtin image now. There is no need to go
through the shadows code manually anymore as regular items do get
shadows automatically.

This also allows simplifying the actual spinner drawing code so that it
actually works.

572f46067f cssstyle: Rename GtkCssComputedValues => GtkCssStyle
This is literally just renaming of the object (and the associated source
files). No other changes are in there.

3759190c26 css: Parse text-shadow values properly
We used to accept the same syntax for text-shadow and icon-shadow as
we accept for box-shadow. However, box-shadow does accept a spread and
the inset keyword while the others should not.

e9fb8ad1f7 css: Fix computation of pixels occupied by blur radius
These computations were done randomly in lots of places and more often
than not, they were also wrong.
This function was copied (with docs) from Firefox:

af2c40bd54 css: Add a scale argument to css-value compute vfunc
We need to be able to compute different GtkCssImage values
depending on the scale, and we need this at compute time so that
we don't need to read any images other than the scale in used (to
e.g. calculate the image size). GtkStyleProviderPrivate is shared
for all style contexts, so its not right.

f478f16dba cds: enable outset shadows
Adds conditional code paths to GdkCssShadowValue for painting outset
shadows, and allows shadows to be applied in two passes (first outset
then inset). This can be used to draw csd shadows in outer window
borders.

a021b72c71 cssshadowsvalue: handle gtk_css_value_transition returning NULL
The implementation of transition for GtkCssShadowValue can return NULL
at least when the two values have a different inset; all other parts of
the GTK/CSS machinery (e.g. GtkCssArrayValue) handle this by returning
NULL too. Instead, GtkCssShadowsValue was returning an invalid value,
where "len" was set, but some values in the array were NULL, which would
lead to a segfault when this value is later evaluated by the compute
function.

Fix this by making GtkCssShadowsValue return NULL if a shadow transition
fails, like GtkCssArrayValue does.

1454ba15ba css: Huge refactoring to avoid computing wrong values
Here's the shortest description of the bug I can come up with:
When computing values, we have 3 kinds of dependencies:
(1) other properties ("currentColor" or em values)
(2) inherited properties ("inherit")
(3) generic things from the theme (@keyframes or @define-color)
Previously, we passed the GtkStyleContext as an argument, because it
provided these 3 things using:
(1) _gtk_style_context_peek_property()
(2) _gtk_style_context_peek_property(gtk_style_context_get_parent())
(3) context->priv->cascade

However, this makes it impossible to lookup values other than the ones
accessible via _gtk_style_context_peek_property(). And this is exactly
what we are doing in gtk_style_context_update_cache(). So when the cache
updates encountered case (1), they were looking up the values from the
wrong style data.

So this large patch essentially does nothing but replace the
context argument in all compute functions with new arguments for the 3
cases above:
(1) values
(2) parent_values
(3) provider

We apparently have a lot of computing code.

e3fc081c5d cssvalue: Pass property ID to transition function
This is to allow animating arrays properly. I'm not really thrilled
about this solution (we leak propertys into the values again...), but
it's the best I can come up with - I prefer it to having N different
array types...

0e2f35ed88 css: Introduce dependencies for value computations
When values are computed, they might depend on various other values and
we need to track this so we can update the values when those other
values change. This is the first step in making that happen.

This patch does not do any dependency tracking at all, instead it uses
GTK_CSS_DEPENDS_ON_EVERYTHING as a sort of FIXME.

9b4ed66218 css: Pass property_id to compute function
This is a reorganization of how value computing should be done.
Previously the GtkCssStyleProperty.compute vfunc was supposed to take
care of special cases when it needed those for computation. However,
this proved to be very complicated in cases where values were nested and
only the last value (of a common type) needed to be special cased.

A common example for this was the fallback handling for unresolvable
colors.

Now, we pass the property's ID along with all compute functions so we
can do the special casing where it's necessary.
Note that no actual changes happen in this commit. This will happen in
follow-ups.

9b953829fb css: Introduce _gtk_css_value_compute()
This commit is essentially a large reorganization. Instead of all value
subtypes having their own compute function, there is the general
_gtk_css_value_compute() function that then calls a vfunc on the
subtype.

ac6d61f6bb cssvalue: Add GtkCssShadowsValue
This is necessary because shadows get treated differently from other
