27b9efbea2 cssimage: Fix size computation for -gtk-icontheme()
For images without a concrete size but with an aspect ratio, we took the
wrong code path.

(I even copied the documentation that said "Otherwise" but didn't put an
else clause there, go me!)

633ec8184d css: Add support for -gtk-icontheme("icon-name")
This allows using icons from the icontheme as images in CSS. The
reasoning is that this allows to give the image control about how it's
scaled (by using the icon theme's scaling method. So we can get crisp
images at different resolutions.

854f5818f8 Sync with changes in the cairo device-scale handling
The version of device scale that landed in upstream cairo
master already inherits the device scale in cairo_create_similar,
so no need to do that in gtk anymore.

499cef1bb0 css: Inherit device scale in _gtk_css_image_get_surface
To handle hidpi support we need to make sure we don't
downscale scaled css images.

Note: If cairo_surface_create_similar starts doing this
by itself we need to back this out.

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.

016647edb1 cssimage: Add a warning for drawing empty images
width and height of an image must be > 0 for the image to get drawn.
It's up to the code further up to ensure that this is not happening.

12683da8f7 gtk: Make functions static that don't need to be non-static
Also remove the starting underscore from function names where
appropriate, as those functions are static now and not exported anymore.

This is part of a bunch of fixes for gcc complaining about
-Wmissing-declarations.

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.

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.

d853a8f2f7 cssimage: Add GtkCssImageCrossFade
Supports the cross-fade() css notation the way the old CSS3 specs did.

The main reason for adding it is supporting image transitions though.
