e58c82fc04 theme-node-drawing: don't crash if st_theme_node_paint() is called on an empty area
When st_theme_node_paint() was called with zero width or height and a theme
node with a shadow, we'd crash because we'd fail to allocate a texture with
an empty size, then unreference the NULL pointer.

0dd4584157 st-texture-cache: Rearrange code to prevent some work and a memory leak
For some reason, the texture cache decides to make a request and then look up
an icon in the icon theme. If it's valid, it just returns, fine, but if it
doesn't add the icon, it tries to undo the request, leaking an
AsyncTextureLoadData that isn't freed in the process.

e49a595f54 st-texture-cache: Don't cache GIcons which cannot be serialized
For GIcons we use g_icon_to_string() in the key, but the function
will return NULL if the icon cannot be serialized. As a result,
all non-serializable GIcons of the same size end up with the same
cache key - an example for this are contacts with avatars, which
currently all end up with the same image.
To fix, opt out of caching for GIcons which cannot be serialized.

325462d9bf St: Take the cairo fallback for large corners
The cogl path pads the corners out to the maximum corner radius to make the
math and painting logic easier. Unfortunately, when the radius exceeds the
actor's halfsize, the padding ends up interfering with other corners, creating
a big mess of rendering errors.

It'd be extremely complicated to fix this properly in the Cogl code,
so take the Cairo fallback.

Use ClutterContainer functions for adding the tooltip instead of
calling clutter_actor_set_parent behind the stage's back, and do
it inside st_widget_show_tooltip (which is a normal method) instead
of overriding st_tooltip_show, which is a vfunc and it is called
internally by Clutter, therefore it is limited in what it can safely
do.
Also, instead of positioning the tooltip with clutter_actor_set_position,
modify the anchor point when the associated widget moves, so that
only a redraw is queued.

d3703516d9 Fix handling of clutter_init() failures
clutter_init() fails under normal circumstances like

Clutter consistently produces an error message when

43cf60f563 StScrollViewFade: Fix GLSL shader to work on r300 hardware
The number instructions in a shader is limited to 64 on r300 hardware,
the fade shader in StScrollViewFade was ending up using 97 instructions
which is way over the limit.

So refactor the shader to use less instructions by precomputing as many
values as possible outside of the conditionals. The resulting shader
ends up using 34 instructions which is well within the hardware limits.

with symbolic icons; if the user's icon theme is not "gnome", then it
will end up preferring a non-symbolic icon from the higher-level theme

If the shell requests a symbolic icon, and there is only a
non-symbolic icon available, that should be considered a programmer
error, just like requesting a non-existent icon name. So change the
code to only look up "-symbolic" names when drawing an

"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

For gradient backgrounds, borders were implemented by filling the

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.

d870fef122 StBoxLayout: report correct paint volume when scrolled
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.

6b723ed72a StImText: add get_paint_volume()
Since StImText isn't a StWidget, it needs it's own implementation
of get_paint_volume() to enable clipped redraws.

56fb7e2c58 St: Take advantage of clipped redraws
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.

1fce237538 StThemeNode: suppress compiler warnings and fix minor bugs
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>.

8734a59cd7 Handle icon theme changes
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.

We were always drawing the border and background of each

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().

af7ba00e97 StIcon: pass in the StThemeNode to get colorized symbolic icons
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.

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.)

3ca86b2197 StIcon: Center the icon rather than scaling it up
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.)

35400238aa StIcon: Always request a square icon size
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.

439d7f036f Port StIcon from MX framework to St framework
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.

StIconType will be used by a new StIcon class, so move it to the
