The shadows are currently rendered by painting the actor we want to
apply shadow on, in an offscreen buffer. The problem is that when this
actor has an allocation padding (ie allocation that isn't at 0x0
relatively to its parent), this padding is added within the offscreen
buffer and as a result the shadow rendering is truncated because the
offscreen buffer size is the size of the allocation box, not the
allocation box + padding.
This patch reposition the actor at 0x0 with rendering it by changing
the initial transformation matrix when rendering the actor offscreen.

This makes it much easier to implement correct popup-menu behavior
in the case of nested bins.
This fixes the context menu key in application search results when a
result has focus.
https://bugzilla.gnome.org/show_bug.cgi?id=699800
The comment clearly intended that for this to be the case, but a typo
prevented this from actually being done. This fixes the focused state
of the search field not working more than once.
https://bugzilla.gnome.org/show_bug.cgi?id=699799
In most cases, we'll transition between two states on hover / focus.
Instead of recalculating and repainting our resources on state change,
simply cache the last state when we transition.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
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.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
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.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
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.
https://bugzilla.gnome.org/show_bug.cgi?id=697274
We want to put the paint state in the actor rather than in the theme
node, as having two actors with different sizes but the same theme node
is now much less efficient.

Similar to the existing generic getter methods, add lookup functions
for URL properties like the standard background-image/border-image
properties.

The changes from commit b4f5f1e461 and b394d184cc increased the
instructions required for the fade fragment shader. This is over the limit
for some hardware (like intel gen3), which causes the driver to fallback
to software rendering for the shader. The result is that painting a scrollview
that has a fade effect takes around 30 (!!) seconds.
So lets go back to the old effect for 3.8 until we find a solution.

Curently it is possible to copy the content of password entries,
and paste it elsewhere in clear text. This is undesirable, so
follow GTK+'s behavior and disable the cut/copy actions for
password entries.
https://bugzilla.gnome.org/show_bug.cgi?id=695104
Since commit b4f5f1e461, the effect is eased in at the scroll
view's edges so that it does not appear out of nowhere. However,
the linear easing used is not the best option, as now the effect
appears so late that content near the edges ends up just being
cut off rather than faded out.
So adjust the easing function to have the effect appear faster.

If enabled, scrollbars take away from the allocation given to the
view's content. This is usually preferrable to painting the bars on
top of the content, but there are exceptions, for instance when the
content needs to be centered with regard to the view as a whole.
Add a :overlay-scrollbars property to account for those cases.
https://bugzilla.gnome.org/show_bug.cgi?id=694261
We cannot reset the cursor at the next leave event, as that might
happen on a NULL stage and cause a BadWindow error, so do it on
unmap (which is guaranteed to happen before the stage is cleared).
https://bugzilla.gnome.org/show_bug.cgi?id=694057
While we were relying on gtk_icon_info_load_icon and friends being
thread-safe, there was no such guarantee, and recent caching that
was added to GTK+ made it non-threadsafe. To replace it, _async()
variants of the icon loading code were added that are thread-safe.
Use those instead of using our own worker threads.

Instead of using Clutter to add an event filter for X events it now
uses the GDK API. The Clutter API won't work if Clutter is not using
an X11-based backend such as if Mutter is directly running with the
KMS backend. This is a step towards making Mutter be its own display
server and a step towards being a Wayland compositor. In this case GDK
will still be using the X backend because it will connect to the
headless X server.

Before version 1.2 of GLSL it would not implicitly convert from int to
float which meant that if you compare a float variable with an integer
constant it will generate a compile error. In particular this means
that on GLES2 (which uses GLSL 1.0) the scroll view shader will not
compile on pedantic compilers, which includes Mesa. This patch just
changes it to use floating point constants.

Cogl sets this for us since commit 2701b93f159bf2d3387cedf2d06fe921ad5641f3.
Setting it twice is illegal and causes compile failures:
error C0204: version directive must be first statement and may not be repeated.
Clutter translates keyboard state internally, and clears the lock bits
from modifier state, so translating again results in the wrong keysym.
Given that Clutter already gives us a fine keysym, we don't need this.

As theme nodes keep a cache of matched properties, we need to make
sure to update it when the list of stylesheets changes. In particular
this fixes a regression from commit dc2ec0a8f9, which caused
extensions with stylesheets to crash the shell when re-enabled (for
instances when coming back from the lock screen).
https://bugzilla.gnome.org/show_bug.cgi?id=692994
StThemeNodes cache matched properties from stylesheets, so when the
list of custom stylesheets changes, the node may miss better matches
(when a stylesheet was added) or have pointers to invalid memory in
the list (when a stylesheet was removed).
In order to allow theme nodes to listen for stylesheet changes, add
an appropriate signal to StTheme.

According to css3-transition, transition-duration is expressed
as a time, that is, in seconds or milliseconds. Fix that by
recognizing numbers with units and implicitly converting to
milliseconds after parsing.

The code here before was added as dummy code to satisfy an error
in the missing switch, and wasn't ever tested due to the lack of XI2
in mutter. Use the same math as GtkRange does to calculate scroll bar
positions from raw XI2 deltas to allow for proper smooth scrolling.
