Loading a pixbuf in a way that cairo can use it is a
pretty involved process that involves a lot of code, and pixel
fiddling.
This commit adds the mechanism to StTextureCache so we can reuse
the existing pixbuf handling code there, and also get caching.

A lot of the border drawing logic in st_theme_node_render_gradient is
applicable to other non-solid background types than gradients.
This commit refactors that code so that support for other non-solid
background types can be more easily integrated later.
https://bugzilla.gnome.org/show_bug.cgi?id=636976
When drawing the background image shadow, we need to clip it
to the node's background color, gradient, or borders if present.
If the background color is transparent, and there aren't any
borders, then we don't clip the shadow since there is nothing
to confine it.
https://bugzilla.gnome.org/show_bug.cgi?id=636976
The border_texture (and border_material) variable is being
overloaded for two purposes: it's used as a source
to 9-slice the border from, and it's used as place to prerender
the background and border together for gradients.
While we only do one or the other for any given node, the two cases
are distinct, and should use distinct variables for readability.
https://bugzilla.gnome.org/show_bug.cgi?id=636976
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.

StWidget reports a paint volume large enough to paint the current
theme node. As CSS transitions also paint the previous theme node,
the reported paint volume may be incorrect, resulting in screen
artifacts when painting outside the reported volume.
Add st_theme_node_transition_get_paint_box() to calculate an allocation
large enough to paint both theme nodes, and use it to report the correct
paint volume during transitions.

Right now is just redefine atk_object_get_name.
If someone wonders why not implement AtkText interface, or expose the
internal ClutterText, here a extract from AtkText doc:
"AtkText should be implemented by AtkObjects on behalf of widgets that
have text content which is either attributed or otherwise
non-trivial. AtkObjects whose text content is simple, unattributed,
and very brief may expose that content via atk_object_get_name
instead;"
StLabel is attributed, but is still simple and brief. In the same way
the atk_object_get_name redefinition is required, so this patch is the
first step. We can implement AtkText in the future.
https://bugzilla.gnome.org/show_bug.cgi?id=626658
It includes:
* Expose a proper focusable state, instead of the default one from
cally, using StWidget::can_focus, and also notifying the state change
* Management of the selected stated, using the current pseudo_class.
* Defines a new virtual method on StWidget: get_accessible_type. In
this way it is not required to reimplement get_accessible just for
a accessible type change. get_accessible is reimplemented using this.
You can see that as a substitute of the atk object factory

Instead of converting a CSS-specified length to an integer by truncation,
round. This means that sizes specified by converting a pixel value into
non-px terms will work reliably instead of potentially being off-by-one.
We weren't freeing the whole pixbuf, nor were we the GList of
subpixbufs. Plug both of these leaks in the error handling path
and in the default case.
All of the unreffing/cleanup should happen in the GDestroyNotify
for the result, not some in the handler.

While non-uniform border widths were parsed correctly, an arbitrary
side's width was picked when painting, so that each border ended up
with the same width and the widths specified in CSS were ignored.
At least for sides between non-rounded corners, using a different
border width can be reasonable, for instance at screen edges.
Different border widths around rounded corners are kind of crack,
but then it would be lame not to support it ...
https://bugzilla.gnome.org/show_bug.cgi?id=607500
For gradient backgrounds, borders were implemented by filling the
background shape with the border color first, and then scaling down
the path to draw the background.
The result is not correct[0], which is especially visible if the border
width is greater than the border radius - so instead of scaling down
the original path, use a separate path for the background.
The result is consistent with the borders we draw for non-gradient
backgrounds, and much closer to the correct standard behavior.

non-absolute paths specified as url()'s in
stylesheets are resolved to be relative to the location
of the stylesheets they are in.
Inline styles don't have physical styleshseets sitting on disk,
which leads to a crash in the url resolving code.
This commit ensures that we don't try to use the stylesheet associated
with a url, if there isn't one to use.
This commit doesn't try to handle relative paths in inline styles.
It only prevents crashes when absolute paths are used.

When scrolled, st_box_layout_apply_transform() includes the scroll
offset and affects paint volumes. This is right for our children, but
our paint volume is determined by our allocation and borders and
doesn't scroll, so we need to reverse-compensate, the same as we do
when painting.
https://bugzilla.gnome.org/show_bug.cgi?id=630932
In order to take advantage of clipped redraws (only redraw the
parts that actually changed), we have to inform clutter about
our paint_volume by implementing the get_paint_volume virtual
method.
As this feature had been added in in clutter 1.5.x we now require
that.
https://bugzilla.gnome.org/show_bug.cgi?id=630932
Aggressive compiler flags can cause the compiler to be smart enough
to inline functions and detect variables not being set on certain
code paths but not smart enough to understand the overall logic;
add some extra initializations to suppress the warnings.
Fix several minor bugs in the logic found when double checking the
logic before adding the initializations.
Based on a patch by Marc-Antoine Perennou <Marc-Antoine@Perennou.com>.

Add a "gicon" property so that a GIcon can be used instead of an
icon name, while still getting icon recoloring from the theme.
Also include a compatibility wrapper in libshell until GJS has
support for interface static methods.
https://bugzilla.gnome.org/show_bug.cgi?id=622451
Connect to the "changed" signal on the default icon theme, and
when it triggers:
- Evict all cached looked up icons from the StTextureCache
- Fake a style change on all StThemeContext; this will result
in StIcon looking up icons again.
https://bugzilla.gnome.org/show_bug.cgi?id=633866
It is not referencing them when adding, and also it is connecting
to the "destroy" signal, emitted on dispose, so there is no risk
of storing finalized objects.
https://bugzilla.gnome.org/show_bug.cgi?id=634781
We were always drawing the border and background of each
StThemeNode, even if they were transparent. The simple
optimization of checking the alpha provides a significant
performance boost (in a quick test, it increased the
overviewFpsSubsequent metric in the core performance test
from 28fps to 35fps).
https://bugzilla.gnome.org/show_bug.cgi?id=634752
Now that we're using St.Icon in the Javascript, there is no reason
to have separate st_texture_cache_load_icon_name() and
st_texture_cache_load_icon_name_for_theme(), instead just add
the StThemeNode argument to st_texture_cache_load_icon_name().
https://bugzilla.gnome.org/show_bug.cgi?id=633866
Use st_texture_cache_load_icon_name_for_theme() so that we get the
right colors for symbolic icons. The code refactoring to achieve this
also avoids constantly starting a new icon load each time we set
a property on initialization ... the icon is loaded only after we
have a #StThemeNode assigned.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Sometimes it's useful to get the theme node if there is one and do
nothing and wait for the ::style-changed signal if there is no theme
node. Add st_widget_peek_theme_node() that just gets the current
theme node if available. The caller must handle a %NULL return.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Add st_texture_cache_load_icon_name_for_theme() which, when loading a
symbolic icon, gets a #StIconColors from the theme node and uses that
to colorize the icon.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
A new StIconColors object is used to efficiently track the colors
we need to colorize a symbolic icon.
st_theme_node_compute_icon_colors() is added to compute the
StIconColors for a theme node. (Refcounting of StIconColors means
that we'll typically share the colors object of the parent node.)
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Scaling up icons from the loaded size to a larger size is uniformly
ugly and results in a long series of "fuzzy icon" bugs. It's better
to just load at the specified size and center. (Centering can be
overridden by packing not-fill in the parent container.)
https://bugzilla.gnome.org/show_bug.cgi?id=633865
We don't want the layout to change when we say, change from
battery-full to battery-full-charging, so we should request a square
based on the icon size unconditionally and not try to adapt to the
size of the texture we loaded. This also means that our layout is
independent of the loaded texure which, if we switch away from
using a ClutterActor child will allow us not queue a relayout when
the icon finishes loading.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
Make StIcon compile and work in St.
Changes:
* ::icon-type and st_icon_set_icon_type are added to allow
specifying SYMBOLIC/FULLCOLOR for an icon.
* Ability to set the icon name from the theme is removed; it
wouldn't easily fit into our framework and two levels of
abstraction between code and image doesn't seem that useful.
* size CSS property is renamed from x-st-icon-size to icon-size
to correspond to what we are doing elsewhere.
* CSS and property based icon sizing are cleanly layered - if
you set the icon-size property, the CSS size is ignored.
* Add a simple JS test of StIcon.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
StIconType will be used by a new StIcon class, so move it to the
header file of common enumerations. Including st-types.h which had
the St single-include check revealed that st-texture-cache.h didn't
have that check and several places were including that directly.
Fix that up.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
The ability to set a "content image" on an icon relies on the ability
to have custom theme properties of a "border image" (9-slice) type.
We don't have this, and the capability of a bordered image specified
by the theme can be achieved more naturally with standard CSS facilities.
