a2fcbb7e65 st-widget: Cache two paint states
In most cases, we'll transition between two states on hover / focus.

c29aaa047d st-theme-node: Move some allocation-independent textures back to the theme node
The background image, background image shadow and border image are
allocation-indepedent, so we can keep these in the node. Given that these are
are likely cached in the StTextureCache, the slight increase in code complexity
may not be worth caching these textures and materials -- we might be better off
just computing when we need to paint.

49064ed56d st: Move the theme node drawing state to StWidget
This ensures that two widgets sharing the same theme node won't trample
on each other's prerendered materials if the actors are of different
sizes. This also tries to be very careful to share as much as possible
during a transition.

This has the side effect that if a widget changes state a bunch of times,
we won't cache every state. Since we expect that state changes are
infrequent and that most cases we'll be able to use the texture cache
to do most of the heavy lifting, this cost is much more insignificant
than rendering a number of different actors with the same theme node
and different sizes.

72bc46d339 st-theme-node-drawing: Move most of the cached paint state to another struct
Since we now share theme nodes between, we shouldn't cache the paint state
across all nodes. As a first step towards putting this in the actor, split
out the state into another structure. Keep it in the theme node for now
so that we don't make too many changes in one commit.

It's possible that some of these pieces of drawing state could be shared
between theme nodes. For the sake of simplicity, assume that none of them
are shared or should be shared. A future commit could identify those that
could be shared and move them back into the theme node.

655dce6a4b st-theme-node: Recalculate properties on stylesheet changes
As theme nodes keep a cache of matched properties, we need to make

this fixes a regression from commit dc2ec0a8f9, which caused

f7af96dbb2 St: avoid blocking IO to resolve relative urls
realpath() does a series of lstat() on each path component to resolve
symbolic links, but we just want to get an absolute path, and we don't

dc2ec0a8f9 Keep similar theme nodes so we don't have to recompute CSS so often
Because we calculate and cache CSS properties once per StThemeNode,
and only a certain set of attributes can affect the CSS properties,
it's advantageous for as many widgets as possible to share a single
StThemeNode. Similarly, if a widget changes state and then changes back
(e.g. gaining and losing the :hover pseudo-class), it should ideally
get its original StThemeNode back again when it returns to the old
state.

Here, I'm using the StThemeContext as the location for a cache.
StThemeNodes are currently never freed: this seems OK for Shell's usage
(a finite number of IDs, classes, pseudo-classes and types).

The material of prerendered backgrounds is now painted in the
rectangle determined by st_theme_node_get_paint_box(). As the
ClutterActorBox returned from that function includes the space

prerender and place the background material.

e727c184ef StThemeNode: Split -st-shadow into three attributes
Currently, "-st-shadow" can mean one of three very
different things:

1) shadow based on alpha of the background image
2) shadow the "border box" of the node
3) shadow applied to the content of a StIcon

It isn't well defined which of the above 3 cases
-st-shadow will mean for any given node, however.

This commit splits the property into three
different properties, "box-shadow",
"-st-background-image-shadow", and "icon-shadow"
to make it all very explicit.

8886b7433c StThemeNode: simplify use of get_color/get_double/get_length
Although within St itself there are situations where the semantics of
these functions (return TRUE or FALSE and return the actual value in
an out parameter) is useful, it's mostly just annoying at the
application level, where you generally know that the CSS property is
going to specified, and there is no especially sane fallback if it's
not.

So rename the current methods to lookup_color, lookup_double, and
lookup_length, and add new get_color, get_double, and get_length
methods that don't take an "inherit" parameter, and return their
values directly. (Well, except for get_color, due to the lack of (out
caller-allocates) in gjs.)

And update the code to use either the old or new methods as appropriate.
