216e996f66 st-theme-node: Unconditionally apply style margins on the actor
We currently don't have any code either in gnome-shell or
gnome-shell-extensions setting margins directly with the Clutter API.

On the other hand, the current behavior doesn't allow us to remove a
style class with margins and have that be reflected, so removing this
special casing seems like the right thing to do at this point.

b58f08bda1 viewSelector: Don't reset the search entry if it has preedit text
If users click outside the search entry while it's empty we reset and
thus give up key focus. This means that when using an input method
with candidate popups, interacting with the popup with a mouse click
cancels the current input method context if there's no other text in
the entry besides the preedit string.

To avoid this we can check if the entry has preedit in addition to
checking if it has normal text.

5bdaffd36e st-private: fix cogl orthographic projection matrix
Commit 1c1f63a7d7 changed the shadow
pipeline to use cogl_framebuffer_ortographic() instead of cogl_ortho(),
but the two functions take their arguments in a different order.

Fixes graphical corruption for text shadows in the login screen.

2940ef07e9 st-theme-node: Add support for -st-icon-style property
GTK+ added support for a -gtk-icon-style property in themes to
enforce a particular icon style. Do the same for shell themes
with an -st-icon-style property, with the same set of possible
values as the GTK+ variant:
  'requested' - use symbolic or fullcolor icon depending on the
                icon name (default)
  'regular'   - enforce fullcolor icons
  'symbolic'  - enforce symbolic icons

2935fd4ffe St: support css margin property
It's implemented similar to the padding property, but instead of taking
into account the margin values at drawing time in node-drawing, we set
the clutter actor margins in StWidget when the style is computed.

In the case that a CSS margin is not specified, we don't to set a value
of 0 to the clutter actor margin. In this manner it allows to use
Clutter margin values set in the code. However, the margins that are set
both in the code and in the CSS on the same side, the result is
unpredictable.

We avoid to set the clutter actor margin values to 0 if there's no CSS
margin values defined, so we still allow clutter actors to use margin
set in the code.

a7aba1d585 st-widget: Sort actors by distance from the focused actor
Sorting actors by the distance in the axis of movement first and against
the axis otherwise means that if we have a situation like:

  A      F
   B

where "F" is the focused actor, and it slightly overlaps with B vertically,
then we'll choose "B" to go left, rather than "A", which is most likely
what the user intended.

This is especially apparent in the overview where slight window size
differences mean we might not get an exact grid shape.

4095a58eb9 st-scroll-view-fade: Reduce number of GLSL uniforms and instructions
The vvalue and hvalue uniforms are only used to decide whether we
should do fade the edges or not based on the fade_edges uniform.
The result does not change accross fragments so there is no reason
to recompute it for every fragment (pixel) so just split the edge
fade into two uniforms and compute the "should we fade the edges"
boolean once for every direction (when setting the uniforms) instead
of for every single fragment twice.

This reduces the number of uniforms as well as the the number of instructions
which are limited on older hardware. It should also be more efficent.

aa394754b6 st: Make BoxLayout use a Clutter layout manager internally
With the BoxLayout containers in St and Mx and the ClutterBoxLayout
manager, we now have three more or less diverged implementations of
the same layout policy.

While removing StBoxLayout entirely in favor of ClutterLayoutManager
would be the fashionable thing to do, there are obvious drawbacks:

 - it is the only actor we have that implements the scrollable interface
 - it conveniently exposes its spacing property in CSS
 - last but not least, it is used all over the place

So do the next best thing and make our implementation use the
Clutter layout manager internally - that way, the change is
transparent to users, while we get to refer most of the tricky
bits to Clutter. win-win!

cba5bca842 st-scroll-view: Unconditionally allocate scrollbars
Commit cfecd063c9 changed the allocation logic to not allocate
scrollbars when the *_visible booleans are false. This breaks the
fade effect as well as the NEVER policy. We do not paint scrollbars
when they are not supposed to be visible, so not allocating them
and thus leaving them in a "needs allocation" state just causes problems.

I am not convinced that it solved any problem to begin with (we don't paint
them anyway).

As the previous condition has basically always been true, just do it
unconditionally.

a18fb27d0f st-theme-node: let paint states take weak ref on theme nodes
When the St theme is changed, the StThemeContext unrefs all the theme
nodes cached in it's internal hash table, then emits a signal to
notify all theme nodes that the current theme has changed.

The problem is that the first StWidget to catch a theme changed signal
will trigger a "style-changed" signal catched by its children first.
So the theme changed signal can't be processed properly to cleanup
StThemeNodePaintState before recomputing the theme.

This patch adds a weak ref to the StThemeNode in the
StThemeNodePaintState to ensure paint states are properly cleaned up
when the associated StThemeNode is freed.

Lionel Landwerlin
318283fc70 st: optimize box-shadow rendering
Currently the box-shadow is rendering is done like this :

The first time we want to render a node that requires a box-shadow, St
creates an cogl offscreen surface of the size of the allocation and
renders the box into this offscreen buffer using modulation on the
alpha channel, this buffer is then blurred according to the CSS
parameters.

The problem with this method is that every time an StWidget is
resized, its box-shadow offscreen buffer has to be resized and
therefore rendered and blurred.

This patches propose an optimization for this use case by rendering
the box-shadow only once but at a size that is independent of the
StWidget's size. Then every time we need to paint this box-shadow, we
just render this offscreen buffer using a 9-slices.

This method only works when the allocation of the widget is bigger
than the minimum shadow size on which we can apply a 9-slices, that is
given my the radius of the corners. If the allocation is smaller than
this minimum size, we then fallback to the fully render/blur the
shadow (like before this patch).

d6fe008b2c st-shadow: Fix offset shadow offscreen rendering
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.

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.

It's possible that some of these pieces of drawing state could be shared

are shared or should be shared. A future commit could identify those that
could be shared and move them back into the theme node.

2cf403a3e9 st-theme: Add "custom-stylesheets-changed" signal
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.

c48a246ccb panel: programmatic anim. control of AnimatedIcon
The AnimatedIcon does not have an API for controlling the animation but
relies on the :visible property changes to start and stop a timeout used
to update the frame.

This has the inconvenient of having a side effect when visible is set to
true multiple times, and is not really the API expected from such
component. Also, there is a race if it is displayed before the images
are loaded: there is no child yet and thus we get this._frame = NaN
which leads to a crash.

Switch to a play/stop API instead, and add a load event callback to the
TextureCache.load_slice_image to exactly know when we can start using
the images.

4fc6a804f5 st_widget_recompute_style: short-circuit if the theme node is the same
It appears to be somewhat common for st_widget_style_changed() to be
called when no style-relevant attributes have, in fact, changed. Now that
we cache theme nodes, we're likely to get the same theme node back from
the cache. If we do, we don't need to waste time asking whether its
geometry and painting are equal to itself: we can just note that nothing
really changed and get on with our lives.

08d2ca300a st_theme_node_copy_cached_paint_state: allow self-assignment
If you copy a theme node's paint state into itself, it should be an
inexpensive no-op. What actually happened was that we destroyed the
old paint state, re-initialized to blank, then copied the blank state
back into itself. In the process, we lost (for instance) the textures
for rounded corners.

Until I introduced the texture cache, this never actually happened,
because when st_widget_recompute_style() calls st_widget_get_theme_node(),
we'd always get a fresh theme node. Now, we get a theme node T back
from the cache, notice that paint_equal(T, T) is true, short-circuit
slightly by copying its drawing state into itself, and destroy drawing
state that we still needed.

I'm going to fix this in recompute_style() too, but as a general
principle, self-assignment ought to be harmless.

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).
