... and Make this new value be a real GValue, as we don't need to save
performance for these anymore (it's just used for custom properties).
And I'd rather have code work for all values then be optimized for no
reason.
Deprecate public API where appropriate and make it no-ops.
Remove all calls to it.
Get rid of the 'transition' css property.
For now, this means spinners don't animate anymore.
Also, in places where we're computing a new CssValue based on an
old one, make sure that if nothing changes we're returning a reference
to the old one, rather than creating a new identical instance.
We now use the GtkStleProviderPrivate interface, which hopefully is
faster and more conformant to CSS. Long term, it definitely should be
both.
I would have liked to split this up into multiple commits, but couldn't
find a way.
We now support -gtk-win32-theme-part(class,part,state) in background
and border-image CSS properties. This renders the corresponding
theme part using DrawThemeBackground() and acts as a base for a
CSS based windows theme.
Note that we build the parsing code even on non-win32 so that
all themese will parse the same on all arches. We draw pink instead
of the actual theme parts on non-win32 though.
We want to move to a world where getting style properties can
allocate a new value, depending on the style property context.
In this world we can't expose "peeking" a property, as we neet
to return a ref to the property that is newly created.
So, we move the peek code into get_property and use get_property
from get_valist.
At the toplevel we have _gtk_theming_engine_get, which lets us pass
in a property context with (atm) the size to get the property for.
Then there is a lot of plumbing to push this down into the lower
layers of the style property code until finally hitting
the property resolvers.
I need this because I will be adding a property resolver for win32
theme parts, and they render differently depending on the size
(i.e. they don't scale linearly). The idea is that the code
to get the background properties will pass in the final size
and we will resolve the theme part specification to that particular
size.
If the old non-context calls are used we just hardcode a size
of 100x100.
It's composed by
- border-image-source: a cairo_pattern_t holding an image from file or a
gradient
- border-image-slice: a GtkBorder containing the slice offsets to apply
on the image
- border-image-repeat: a GtkRepeatType for the image
We deviate from pure CSS3 in the following ways:
* border-image-width is assumed to be always 1, i.e. always equal to
what's specified by border-width. I don't think it's a particularly
useful property to have, but we could add it later if needed.
* border-image-outset is absent, as we can't render outside of the
allocation yet.

Inheritance is now done using style property flags, so thereis no ned
anymore to clobber the pspec flags namespace.
Also, there is no need to expose this functionality in the public API
without exposing more of the styleproperty API.
This essentially reverts commit 9bfd3d2eec.
