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.
https://bugzilla.gnome.org/show_bug.cgi?id=633865
ST makes use of GTK+ for input methods and for icon themes; therefore
we have need to initialize GTK+ in order to test these parts of Clutter.
Instead of LD_PRELOADING our module, use a separately compiled executable
that links to the UI components in GNOME Shell, initializes Clutter and
GTK+ and hooks them together.
Getting all the symbols from St and the GUI components exported for
use via GJS requires a bit of contortion: we need to actually link the
St convenience library into a shared library and link the executable
to that since there is no way with libtool to take a convenience library
and put all its symbols into an executable --whole-archive style.

* Make sure all source files have a LGPL copyright header, and standardize

We weren't properly nulling out the vadjustment variable in dispose()
which meant in the case of explicit-destroy followed some time later
by garbage collection and disposing the actor again we would crash.
Use StWidget:track-hover rather than doing it ourselves. Don't assume
that hover is always TRUE after an enter_event or FALSE after a
leave_event, since we have a pointer grab and will be getting other
actors' events.
Don't ungrab the pointer when it leaves the button, since that
destroys the whole point of getting a grab in the first place.
Only consider the button to have been clicked when it has both grab
(meaning the mouse was pressed over the button) and hover (meaning the
mouse was released over the button).
Also remove the virtual pressed/released methods, which weren't being
used anyway.

Like all X API, XFixesGetCursorImage returns arrays of 32-bit

In d66e7dd49 I got confused between border_texture and
background_texture. The background_texture was being created as normal
but in the one place that it gets drawn I accidentally made it use the
border_material instead. This patch makes it create a
background_material similar to the border_material and uses it to
paint.
A few places in st-theme-node-drawing create one-shot material, paint
with it and then free it. This is suboptimal with current Cogl because
it will end up compiling an ARBfp program just for that single paint
and then it will throw it away when the material is destroyed.
There is a new function in st-private.c called
_st_create_texture_material. This creates a simple material for a
texture based on a common parent material that points to a dummy
texture. Any materials created with this function are likely to be
able to share the same program unless the material is further modified
to contain a different number of layers. It would be possible to use
cogl_set_source_texture for this instead except that it's not possible
to modify the material's color in that case so we couldn't render the
texture with opacity.
The corner textures are now stored as a handle to a material that
references the texture rather than storing the texure directly. There
is also a separate border_material member which always points to
border_texture as the only layer.

Plugging the GtkSocket icon can fail, in which case NaTrayManager emits
tray-icon-removed but the icon has never emitted plug-added, thus the

MutterWindow and MutterPlugin have been renamed to MetaWindowActor

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.
https://bugzilla.gnome.org/show_bug.cgi?id=632590
Gjs changed to separate the "basic" API from "embedder" API. Unfortunately
due to our use of the importer API and a few other bits, we need to use
the "module" one. In the future I plan to extend the core API to
support this use case.
Add volume control indicator which uses API from gnome-volume-control
to interact with PulseAudio and shows both input and output volumes.
Also adds a small wrapper around libcanberra in ShellGlobal, used by the

st-theme stores some loaded stylesheets in a custom
stylesheets list. When removing items from this list
it unrefs them, but when adding items to the list it

StDrawingArea uses the member variable needs_repaint to keep track
of whether it needs repainting. The variable is set to TRUE correctly,
e.g. on allocation or style changes - alas, it is never set to FALSE,

Since we're just using a cut-and-paste of gdm code there's a
slight impedance mismatch between how that code and the rest of
the shell manage debug messages. In GDM, they're out of sight by
default, but in gnome-shell they're visible and quite verbose.
This muddies up and masks the useful messages that other parts
of the code generate.
This commit just mutes the messages unconditionally by default,
since they aren't that useful anyway.
The GDM code upstream talks to the account service now,
has better introspection annotations, and is more
asynchronous.
This commit updates the shell's copy to the latest
upstream.
Note, the API changed somewhat and so the callers will
need to be fixed up subsequently.

Non-uniform border-radii are already supported when using a gradient

Icons can be loaded as St.Icon.SYMBOLIC, FULLCOLOR, APPLICATION or
DOCUMENT. The first will look for a symbolic equivalent, the second
looks for a full-color version (and does fallback, eg, from

full-color icons without fallback (as specified by the icon spec).
And update various callers to use the right flags.

The actor emitted by ShellTrayManager is now ShellTrayIcon, a subclass
of ShellGtkEmbed which has several properties on it which are (or will
soon be) useful to the shell.
Part of the rearranging to use ShellTrayIcon means that we now show
the ShellEmbeddedWindow before creating its ShellGtkEmbed, which
requires a few modifications to ShellEmbeddedWindow (notably, telling
it at construct time what stage it will be drawn on, since it needs to
know that before it has a ShellGtkEmbed now).

Previously the code to keep the X window aligned with its actor made
various assumptions that were true in the panel status tray area but
that are not true in the message tray. Fix it up by repositioning the

called every time the actor moves, whether it's because of its own or
its parent/ancestor's changes.

As of 1.4, ClutterGLXTexturePixmap is identical to
ClutterX11TexturePixmap (with the differences having been moved into

Add st_theme_node_paint_equal() and use that to do two things:

Creating an FBO may be expensive, so we should avoid the operation
if possible. When transitioning between theme nodes, the widget's
opacity is used to paint to the offscreen textures which are blended
together - this means that the textures have to be recreated each time
the widget's opacity changes. It is much more effective to paint the
textures at full opacity and respect the widget's paint opacity when
blending the textures together.

The current search system uses the OR operator to concatenate search

gdk_screen_get_rgb_colormap() has been removed from GTK+; there's
no longer a special visual that is used for drawing true-color

fall through to the case where we create a new GdkColormap.

The internal ordering of the container's children is used to determine

Windows are only added to an application if they are considered

Use GSettings for all Shell configuration. GConf is kept to read
configuration from external programs (Metacity, Nautilus and Magnifier),
but ShellGConf is removed because it's mostly useless for the few calls

A basic GConf schema is still used to override Metacity defaults and
configure Magnifier in a system-wide fashion. GConf is also used as
GSettings backend via the GSETTINGS_BACKEND environment variable.
All of this will be removed when these programs have been ported
to GSettings and able to use dconf.
GLib 2.25.9 is required. Schemas are converted to the new XML format,

Our behavior of reversing the animation when the widget's style
changes back to the previous one is sound. On the other hand, when
there's a change to a new style while a transition is active, we
simply cancel the ongoing transition. Updating the transition
correctly so that the new one starts from an intermediate state
is hard.
Nevertheless, if the style changes before any time of the transition
has elapsed, we should do better than the current behavior.

First, we were passing an incorrect timestamp to
meta_display_focus_the_no_focus_window - fix that.
The invocation of set_focus_app to the started app there couldn't
really work, because (if the above call had worked) we'd get the
X reply *after* the started app.
What we need to untangle here is the distinction that's now made in
ShellApp between _STATE_STARTING and _STATE_RUNNING. A nice way to
start doing this is to rebase ShellWindowTracker to only be concerned
with app states. Concretely, the current "has windows implies
running" logic now lives just inside shell-app.c.
Rename the app-running-changed signal to be app-state-changed. This
will ultimately be useful so that inside the panel, we can track
the last started app.

The recorded event includes the actual timestamp of the swap, since
we are given that in the GLX event - on my system it tends to be

in a perf module to a single METRICS array. This is done so the
perf module can define the units for each metric.
In addition to improving the output in the web interface, the purpose
of having units is to give some clue about how to pick from multiple
values from different runs. In particular, with the assumption that
"noise" on the system will increase run times, for time values we want
to pick the smallest values, while for "rate" values, we want to pick
the largest value.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add --perf-output=<filename> option to gnome-shell that combines
the reports written for each run by the C/Javascript code into
a complete report.
If this option is not specified, a brief human-readable summary
is printed to stdout instead.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
When SHELL_PERF_OUTPUT is set, instead of just dumping out the metrics, dump
a more complete report with:
- Event descriptions
- Metric descriptions and value
- Event log
Helper functions shell_perf_log_dump_events() and shell_perf_log_dump_log()
are added to ShellPerfLog to support this. The gnome-shell wrapper is adapted
to deal with the changed report format.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Add a helper function to write a string as UTF-8 to a GOutputStream.
The signature of GOutputStream:
gboolean g_output_stream_write_all (GOutputStream *stream,
const void *buffer,
gsize count,
gsize *bytes_written,
GCancellable *cancellable,
GError **error);
Can't currently be handled by GJS.

Add gnome-shell options:
--perf-iters=ITERS"
Numbers of iterations of performance module to run
--perf-warmup
Run a dry run before performance tests
Make a successful run of a performance test return 0 not non-zero,
and handle the difference between that and a 0-exit in normal
usage (meaning replaced) in the wrapper.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
Move the code that starts gnome-shell and waits for it to exit
to a function in preparation for running it multiple times when
doing iterations of a performance test.

Add some basic statistics for allocated memory based on mallinfo(),
and use that to define two metrics:
usedAfterOverview: bytes used after the overview is shown once
leakedAfterOverview: additional bytes used when the overview is
shown a second time.

Add a facility for defining and recording numeric statistics
as performance events
shell_perf_log_define_statistic()
Define a statistic and the corresponding event type
shell_perf_log_update_statistic_[ix]() -
Update the stored statistic value
shell_perf_log_add_statistics_callback()
Add a function called before collecting statistics
shell_perf_collect_statistics()
Update statistics and record events for them
In addition to the explicit collection, statistics are
recorded at a periodic interval (currently 5s)

We want to be able to summarize the behavior of the shell's
performance in a series of "metrics", like the latency between
clicking on the Activities button and seeing a response.
This patch adds the ability to create a script under perf/
in a special format that automates a series of actions in the
shell, writing events to the performance log, then collects
statistics as the log as replayed and turns them into a set
of metrics.
The script is then executed by running as gnome-shell
--perf=<script>.
The 'core' script which is added here will be the primary
performance measurement script that we use for shell performance
regression testing; right now it has a couple of placeholder
metrics.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
ShellPerfLog provides a way for different parts of the code to
record information for subsequent analysis and interactive
exploration. Events exist of a timestamp, an event ID, and
arguments to the event.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
To support scheduling performance-measurement scripts that want to run
a number of actions in series, add shell_global_run_at_leisure() to run
a callback when all work is finished.
The initial implementation of this is not that accurate: we track
business in Tweener.js via new shell_global_begin_work(),
shell_global_end_work() functions, and we also handle the case
where the main loop is continually busy.
https://bugzilla.gnome.org/show_bug.cgi?id=618189
The API docs for ShellApp claimed it sorted by the last time the
user interacted with the app, but if one closed a window, then
we would fall back to comparing against a possibly much older
timestamp from another window. Fix this by just keeping a
user time per app.
Also clean up the comparison function to explicitly check the state
instead of deferring to the window list.
https://bugzilla.gnome.org/show_bug.cgi?id=618378
The ShellGlobal initialization performs several actions like connecting
to the X server, ensuring directories exist, etc., that are problematic
because we were creating the object even when running the binary for
introspection scanning. During compilation we may not even have X11
available in e.g. autobuilder type environments, and it's just a
bad idea to connect even if we do.
Avoid this by deferring creation of the ShellGlobal object
until the plugin is actually started.
Now that we're initializing things later, remove the connection to
screen changes, and initialize cached ShellGlobal state at the point
when the plugin is set. The root pixmap actor is now sized initially
on creation too. Instead of relying on screen-size-changed being
emitted on startup, explicitly invoke _relayout().
https://bugzilla.gnome.org/show_bug.cgi?id=618371
I have no idea why there existed code that if we saw e.g. min-width
without a width, we assigned min-width to ->width, thus effectively
treating it as a maximum.

Starting with gtk-2.20.0 there is a gdk_screen_get_primary_monitor,
which supports querying the primary monitor from xrandr.
But due to a sorting bug and lack of heuristics in the fallback path,
it isn't really useable.
Those bugs are fixed in gtk-2.20.1, so use it when building with
gtk-2.20.1+.

Passing an explicit width in the wfh case or a height in the hfw case
messes up the request caching, and confuses actors that assume they
won't be called with an explicit width/height unless they're being
allocated along the other axis.

Adds the ability to create one or more zoom regions that show magnified or
enhanced views of the desktop. The magnifier provides options for:
* magnification factor,
* four mouse tracking modes common to screen magnifiers,
* positioning the magnified view in one of four screen location, or full screen,
* crosshairs to accentuate the position of the mouse,
* user preferences persistence via GConf (schemas in
.../data/gnome-shell.schemas).
* a DBus API to allow other processes to drive the magnifier as a service.

Add StContainer, which implements the ClutterContainer interface based
on the container methods in st-private and make the existing containers

https://bugzilla.gnome.org/show_bug.cgi?id=613907
To replace all calls to deprecated code, GTK+ 2.20 is required - add
some basic compatibility code, so that is still possible to build the
shell with GTK+ 2.18 when not using -DGSEAL_ENABLE.
https://bugzilla.gnome.org/show_bug.cgi?id=618258
With the transition to GTK+ 3.0, direct access to struct members
will no longer be possible.
This bumps the required minimum version of GTK+ to 2.20.

The StTable code only supports height-for-width. When called in
width-for-height sizing mode, instead of treating the -1 flag
value of 'for_width' as a real width, and requesting all the
children at 1 pixel wide, use the natural width of the table
as the width for determing the height.
Since we can't rewrap in width-for-height mode, we then report
the natural width also as the minimum width of the table.

The design calls for raising all windows for a given app in
certain circumstances; implement this. The new _focus method
raises all windows for the app if it's running.
We further change the _activate method (which a lot of the shell
UI calls now) to invoke _focus for the running case, which means
that e.g. the application well will now raise all app windows.

When creating the directory to store user data, XDG_DATA_HOME is
not guaranteed to exist. Also, the standard mandates permissions
of 0700 for the directory.
https://bugzilla.gnome.org/show_bug.cgi?id=617555
As StEntry handles hover differently depending on whether it is
activated or not, the generic hover support in StWidget is
insufficient. Nevertheless it makes sense to set the hover status
using StWidget methods instead of setting the pseudo class directly.
While the extension system already uses an XDG location (XDG_CONFIG_HOME),
other components use the deprecated $HOME/.gnome2 directory.
Replace both with XDG_DATA_HOME - the existing data (app usage stats,
looking glass history and extensions) is not migrated to the new location.

The (optional) spread radius allows to make the shadow bigger without
enlarging the blur value. Mozilla supports this parameter for the

To avoid visual duplication with the application menu, eliminate
the window menu button. (The window menu can still be accessed by
right-clicking on the title bar, or Alt-right-clicking anywhere on the
window.)
This is implemented using the new Mutter facility for GConf key
redirection; we add separate key for 'button_layout' with a default
that omits the menu button.
https://bugzilla.gnome.org/show_bug.cgi?id=591390
With the changes from bug 615586, Mutter now expects a separate start()
method which is called after construction. Move our initialization from
constructed() to start() so it can access the MetaScreen.
https://bugzilla.gnome.org/show_bug.cgi?id=615592
This patch combines several high level changes which are conceptually
independent but in practice rather intertwined.
* Add a "state" property to ShellApp which reflects whether it's
stopped, starting, or started. This will allow us to later clean
up all the callers that are using ".get_windows().length > 0" as
a proxy for this property
* Replace shell_app_launch with shell_app_activate and shell_app_open_new_window
A lot of code was calling .launch, but it's signficantly clearer
if we call this ".open_new_window()", and later if we gain the ability
to call into an application's menu, we can implement this correctly rather
than trying to update all .launch callers.
* Because ShellApp now has a "starting" state, rebase panel.js on top of
this so that when we get a startup-notification sequence for an app
and transition it to starting, it becomes the focus app, and panel.js
cleanly just tracks the focus app, rather than bouncing between SN
sequences. This removes display of non-app startup sequences, which
I consider an acceptable action in light of the committed changes
to startup-notification and GTK+.
https://bugzilla.gnome.org/show_bug.cgi?id=614755
We can't use gdk_display_get_pointer/gdk_window_get_pointer from gjs
when XKB is active. We already had a wrapper that did the
get-modifier-state part of that, but some places also need the
get-pointer-location part of it. So update our wrapper to return both,
and update js code to use it.
https://bugzilla.gnome.org/show_bug.cgi?id=613428
Also, remove a lot of cruft from genericDisplay.js leftover from
previous St-ifications, and remove the pre-gtk-2.16 hacks from the
status tray in panel.js (which are much less needed with the
nearly-all-black panel anyway).
https://bugzilla.gnome.org/show_bug.cgi?id=614516
The actual changes to shell-menu.[ch] are pretty minimal; most of the
changes there are just style/spacing/indentation.
Also, removed shell_menu_append_separator() since it wasn't needed;
the separators would already have been behaving as intended just
because they were non-reactive.
https://bugzilla.gnome.org/show_bug.cgi?id=614516
Most subclasses override get_preferred_width/height, but if they don't
(eg, StDrawingArea), then make sure they still take CSS-specified
sizes into account.
https://bugzilla.gnome.org/show_bug.cgi?id=614516
StThemeNode holds a reference to its parent, but we never released
that reference. This could cause us to hold onto whole chains
of theme nodes with rather dire memory usage implications.
Also move the other g_object_unref into _dispose.
https://bugzilla.gnome.org/show_bug.cgi?id=614660
Currently shell_global_get_primary_monitor just returns the first screen,
in the list as primary.
This is not always correct as the first screen reported by mutter isn't always,
the first one listed by RANDR.
Use gdk_screen_* to query the monitor information and add a heuristic to prefer
LVDS displays (similar like in done for gnome-panel) to prefer the laptop's
internal screen over external displays.
https://bugzilla.gnome.org/show_bug.cgi?id=608647
Ok, there admittedly wasn't a strong rationale for having it in a
later, and by performing this immediately we reduce race conditions
for our focus_app versus startup_notification handling.

Paint/pick all children, regardless of whether or not they lie within
the content_box. The previous behavior was that a child that was 99%
outside the box would be fully visible, but a child that was 100%
outside the box would be fully hidden. This is somewhat odd, and
doesn't match the behavior of the other St container classes, and at
any rate, the use of clutter_actor_get_allocation_box() for this
optimization was incorrect since it doesn't take into account
transformations (anchor point, rotation, etc) that might cause the
child to be drawn within the content_box anyway.
(For scrolled StBoxLayouts, drawing is still clipped to the
content_box, as before, but will now properly take transformations
into account as well.)
https://bugzilla.gnome.org/show_bug.cgi?id=614047
When the window's top-left corner is the same as the monitor's top-left
corner the check in shell_global_get_focus_monitor fails to detect that.
Use <= rather than < to fix that.

The idea behind this move is that we have a lot more control over
rendering if StWidget isn't a big pile of actors, and things are
more efficient.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
The hover rewrite added a freeze/thaw_notify to
st_clickable_leave_event() (to match the one already in
st_clickable_enter_event()), which broke code in two places that
assumed "pressed" would still be TRUE when "hover" changed to FALSE.
Fix that by exposing the "held" property as well.
A pointer does not equal to an int on x86_64
(which results into pointer - pointer not being an int either),
fix that by casting the resulting value to an int.
Breakage was introduced by commit 909b5ec43c
If track-hover is set, update the hover property automatically, and
the "hover" pseudo class to match, as StClickable used to do. (Remove
the corresponding code in StClickable). Tweak the tooltip handling to
use track-hover, which also makes it slightly more reliable in the
presence of reactive children, etc.
Since style_class and pseudo_class are space-separated lists of names,
add new methods to add and remove individual names rather than just
re-setting the entire name.
Update existing code to use the new pseudo-class methods where
appropriate. In some cases, this may result in actors having multiple
pseudoclasses where previously they only had one at a time, but there
don't seem to be any visible differences.
(There are some places that could usefully use the new style_class
methods as well, but this patch doesn't change them.)
Also, update test-theme.c to test the new methods.

The way we were loading data into a CoglTexture, then pulling it out
and manipulating it on the CPU, then loading it back into a texture
was a bit lame.
Clean things up a bit here by loading directly into the CPU, doing
the fading, then creating a texture.
Also cache the faded data in StTextureCache.

If we don't do this, then boolean/int/list keys will seem to sort of

The relationship between adjustments and scrollbars and
scrollable widgets was much more complex than it needed to be.
StScrollView: Have the scroll view own a pair of adjustments,
set them on the child on add(), remove unnecessary
change notification signal connections.
StBoxLayout: Remove auto-create of adjustments, just take the
adjustments from the scrollbars and set them on the scrollable
child. Notify for hadjustment/vadjustment properties.
StScrollBar: Notify adjustment property.
StScrollable: Document how adjustment setting works.

* ShellGenericContainer needs to destroy its children in dispose()
* Fix variable naming and excess casts in st_label_dispose()
https://bugzilla.gnome.org/show_bug.cgi?id=612511
StScrollable: Document how to set adjustments
StBoxLayout: Make sure that we always have upper >= lower + page_size,
so that clamping works properly. Set the page_increment to be slightly
less than the page_size so there is some overlap, as is customary.
StScrollView: Remove unnecessary fabs() calls, rewrite expressions
for additional clarity.
https://bugzilla.gnome.org/show_bug.cgi?id=611740
- Fix existing typos and spacing problems
- Get preferred height, not current height, of shadows
- Let shadows overflow don't clamp them when we have too little space
- Remove a now-unecessary stray MAX()
- Fix up scrollview visibility for the pathological case of no child
- Disconnect from adjustments on remove()
- Don't unset the adjustments on the child on remove(), since they
already existed or were autocreated on add()
(We should what we are doing and set the adjustments of the
scrollbars on the child rather than setting the adjustments of
the child, so we match GTK+'s scrolllable interface, but this
at least makes it consistent instead of a weird mix.)
https://bugzilla.gnome.org/show_bug.cgi?id=611740
StScrollable: Document how size negotation now works between the
parent and scrollable child.
StBoxLayout: Adapt to the new contract for how size negotiation
works; in particular, handle being allocated less than the
minimum size when scrolled and treat the minimum size as the
size of the scrolled area in instead of the natural size.
StScrollView: Substantially rewrite with fixes including:
- Implement new size negotation contract; this allows us
to determine scrollbar visibility without having to
connect to the adjustment.
- Implement all ALWAYS along with the existing NEVER/AUTO
- When hiding and showing scrollbars and shadows, don't
hide and show widgets, just turn on and off including them
in pick and paint. This avoids queueing relayouts.
- Cleanups for the code for connecting to adjustments,
for changing policy, and for turning on and off shadows.
scroll-view-sizing.js: New test case for StScrollView, allowing
resizing the scroll view interactively, changing the scrollbar
policies and turning shadows on and off.
https://bugzilla.gnome.org/show_bug.cgi?id=611740
When an StScrollView is allocated, allocating the child would
cause the adjustment values to change, which would result in
the scrollbars queueing a relayout, which isn't allowed during
allocation.
To avoid this, instead of queueing a relayout when the adjustment
changes:
- When we have a valid allocation already, just go ahead
and reallocate the children.
- Otherwise do nothing immediately and wait until we get allocated
Because the 'needs_allocation' flag in ClutterActor isn't exposed,
this requires some slightly ugly code to shadow that state locally.
https://bugzilla.gnome.org/show_bug.cgi?id=611944
Having StDrawingArea use ClutterCairoTexture causes circularity
problems with sizing - StDrawingArea wants to use its allocation for
the size of the texture, but ClutterTexture wants to use the size of
the texture to determine the requited size.
Avoid this by making StDrawingArea directly use Cairo and CoglTexture;
while doing this, the API is changed a bit for simplicity and to
match our use case:
- Instead of clutter_cairo_texture_create(), we have
st_drawing_area_get_context() to retrieve an already created
context. This can only be called in the ::repaint signal.
- The ::redraw signal is changed to ::repaint so we can have
st_drawing_area_queue_repaint() that doesn't collide with
clutter_actor_queue_redraw()
- ::repaint is now emitted lazily when painting the actor rather
than synchronously at various different points.
https://bugzilla.gnome.org/show_bug.cgi?id=611750
- Specify a minimum version of clutter-1.2.0
- Switch clutter branch in the moduleset to master
- Replace deprecated cogl_texture/material_unref() with

- Replace cogl_check_extension() with strstr - should be
accurate enough.

It's wrong to do anything that requires looking up a widget's style
before you add the widget to the stage, since its final style may

many would-be contributors apparently didn't notice. Help them out.

StButton animated the background for button transitions; since these aren't

Rather than having ShellTextureCache know about the type of each
item it's caching, this lays the foundation for simply caching
arbitrary string -> CoglHandle.
https://bugzilla.gnome.org/show_bug.cgi?id=607500
For StWidget we want the ability to load raw CoglHandle references
rather than having a big pile of actors backing StWidget.
Several bits of StWidget expect to be able to synchronously load
textures; this is a crutch to support that until we can cleanly
make this asynchronous.

Brute force merge these two by essentially replacing St.TextureCache
with a (renamed) Shell.TextureCache.
One function was added for convenience, namely "st_texture_cache_load_file_simple".
St.TextureCache had a function to load a texture from a filename, and it
returned NULL on error but only half the callers actually checked this. This
function is better.

Since shell-slicer.h includes st.h, and that includes
<st/*.h>, we need to add -I $(srcdir) to the command line when
running g-ir-scanner to generate Shell-1.0.gir.
For srcdir != builddir, in the builddir, the st/ subdirectory doesn't
exist, so we can't generate st.h there. Just switch to building st.h
directly in the current directory. (The other option would be to
create a st/ subdirectory in the builddir if necessary; might be a
little cleaner, but this works for now and gets things distchecking.)
Add a 'vshadow' property to StScrollView, which, when turned on,

Previously we were hacking out the vertical scrollbar, this patch
allow us to sanely say in which directions we want to scroll.

st_theme_node_adjust_preferred_width/height now limit the content area

https://bugzilla.gnome.org/show_bug.cgi?id=606755
In StBin, StBoxLayout, and StTable, if a child has a potential
allocation that is larger than its preferred size, we give it its
preferred size instead. However, the corresponding
get_preferred_height/width methods were not making the same
assumption, which meant that if we had more width than the widget
wanted, we would allocate it its preferred width, but with the height
that corresponded to the larger width.
Fix this by defining new helpers _st_actor_get_preferred_width() and
_st_actor_get_preferred_height() and using them everywhere. Also, make
StBin and StTable use _st_allocate_fill() rather than having
nearly-identical duplicate copies of the code.

In some situations we might need to look up an application from

By calling clutter_actor_get_allocation() in st_widget_recompute_style()
to determine whether to redraw gradients, we triggered a complete
reallocation of the stage for each gradient.
As gradients are processed in st_widget_real_style_changed() anyway, the
additional checks in st_widget_recompute_style() are redundant and can
