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.

2674d96e54 StTheme: retrive the list of custom stylesheets and use it in loadTheme()
Using the list of stylesheets loaded with st_theme_load_stylesheet(),
one can build an StTheme that is completely identical to the previous
one, except for one property (application-stylesheet).
This allows rt and the user-theme extension to work while respecting

e7289378b7 st-scroll-view: Make the fade effect and offset themable
Theme authors now have the power (and responsibility) of creating fade
effects with the new CSS length property '-st-fade-offset'. A value of
0 disables the effect.

This new CSS approach replaces the current programmatic toggle of
the 'vfade' property. A new CSS style class name 'vfade' is used as
a replacement for the old property.

case, setting the text has a visible side effect (dropping the

087e86fb32 StTooltip: fix various warnings and use Clutter API correctly
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.

e886a3d891 StButton: fix handling of Space/Enter -> click
StButton was mistakenly considering any Space/Enter KEY_RELEASE to be
a click, when in fact it should only count as a click if it also got
the corresponding KEY_PRESS as well. This meant that when typing in a
chat notification, any Space/Enter keypress would dismiss the
notification, since the StEntry would take the PRESS event but ignore
the RELEASE, allowing it to propagate to the notification itself,
which would treat it as a click.

026fc531ba StTextureCache: never return fullcolor icons for ST_ICON_SYMBOLIC
g_themed_icon_new_with_default_fallbacks() does not do what we want
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
over a symbolic icon from gnome-icon-theme-symbolic.

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
ST_ICON_SYMBOLIC icon.

ab80c5080a theme-node: Fix box-shadows for prerendered textures
The material of prerendered backgrounds is now painted in the
rectangle determined by st_theme_node_get_paint_box(). As the
ClutterActorBox returned from that function includes the space
needed to draw the box shadow, the background ends up occluding
the shadow.
As the box shadow is not part of the background, factor out a new
helper function which excludes the box shadow, and use it to
prerender and place the background material.

1. Both functions leaked the nodes in priv->children
2. st_container_remove_all wasn't properly updating first_child and last_child
3. remove_all() is almost never right since it won't cause signal handlers
   on the children to be removed. In the rare cases where it might be needed
   the caller can simply use clutter_container_remove().

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.

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.

which meant in the case of explicit-destroy followed some time later
by garbage collection and disposing the actor again we would crash.

4f1f226828 StButton: fix hover and grab tracking
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.

8872913665 StThemeNode: Fix the confusion between border and background
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.

d66e7dd49e st-theme-node-drawing: Don't create lots of one-shot materials
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.

8886b7433c StThemeNode: simplify use of get_color/get_double/get_length
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.

won't be called with an explicit width/height unless they're being
allocated along the other axis.

75b52d36f2 Do something reasonable for width-for-height sizing
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.

1dd4c7140e StBoxLayout: remove an incorrect drawing optimization
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.)

ffd25fe9e4 Fix size negotiation for StScrollView
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.

524e2ca8e2 [StScrollBar] avoid queueing a relayout during allocation
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.

33dca51650 Rework StDrawingArea not to use ClutterCairoTexture
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.

5331d3e360 [St] Make allocation handling more consistent
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

d7e0051bc6 [StButton] Hold ref to self until animation completes
StButton has an internal animation for the border-image actor, then
it connects to the "completed" signal passing itself as data.  However,
if the button is destroyed, nothing prevents the animation's completed
signal from then causing a reference to freed memory.

Holding a reference to the button is the most straightforward fix here.

59d6029f47 Implement radial gradients for StWidget
Some theme authors have stated interest in radial gradient backgrounds.
The w3c has some draft:

http://dev.w3.org/csswg/css3-images/#radial-gradients

As this is rather complex, we add only some very basic support, which
extends our syntax for linear gradients:

background-gradient-direction: [vertical|horizontal|radial]

Gradients are centered circles, whose size is determined by the closest
side.

Some changes to the way we handle CSS gradients:

 * draw without padding, thus interpreting gradients as part of the

 * clip to (rounded) border area

 * draw the border along the gradient instead of trying to align the
   gradient layer with the background/border layer

 * use the border_image actor instead of the background_image one

7239eb2f90 [StThemeNode] Add support for 'width' and 'height' CSS properties.
The behavior in respect to borders matches CSS - the properties set the size of
the content exclusive of the borders (CSS3 box-sizing property - not implemented
here - changes this).

min-width/min-height correspond very closely to the CSS meanings.

width/height are a little different from the CSS meanings - the CSS meaning is
"exactly this size unless overridden by min/max-width/height" - but within the
realm of our layout algorithm, making them control natural size is pretty
close.

This way we can force elements to have a fixed natural or minimum size.

ab0460ad59 Use clutter_actor_destroy in dispose, add _dispose where needed
ClutterGroup calls _destroy, but most of St was just calling _unparent.
This caused problems because the DESTROY signal was not emitted
for child elements after destroying a toplevel.  Also, in a GC'd
binding it would cause unpredictable lifetime of children.

Some St widgets simply didn't have _dispose at all; implement it.

Note because of the usage of the background_image in StButton,
we can't cleanly destroy it inside the StWidget.

clip-to-allocation is removed from StScrollView since it's just

1ec8e9eb6b Allow StBoxLayout to shrink down to its minimum size
When a StBoxLayout is allocated a size less than its natural size,
think "shrink" needs to be divided among the children that have
a smaller minimum size than natural size.

This is done by preferentially shrinking the children that are most
expanded from their minimum size and then increasing that set of
children until we've found enough total shrink.

A new method is used of allocating children at integral sizes - instead
of rounding the per-child extra amount to an integer (which causes
cumulative round-off errors), compute the position as we go along in
floats and round individually for each child widget.

Extend the box-layout test to include of a test of a box being set
to various widths, starting quite narrow.

the box is first allocated.

a9fd350396 Port our imported parts of Mx to ShellTheme
ShellTheme replaces both StStyle and ccss_stylesheet_t.

The interface StStylable is replaced by usage of ShellThemeNode.
A concrete node class allows some significant optimizations of property
inheritance that would have been much more difficult to achieve with
the highly abstract pair of StStylable and ccss_node_t.

Some operations that were previously on StStylable (like the
::style-changed signal) are directly on NtkWidget.

Custom properties are no longer registered as param-specs; instead you
call directly into shell theme node to look up a length or color:

shell_theme_node_get_length (theme_node, "border-spacing", FALSE, &spacing);

The dependency on libccss is dropped, while preserving all existing
functionality and adding proper parsing and inheritance of font properties
and proper inheritance for the 'color' property.

Some more javascript tests for CSS functionality are added; workarounds for
a CSS bug where *.some-class was needed instead of .some-class are removed.

Import:

  HippoCanvasTheme      => StTheme
  HippoCanvasThemeImage => StThemeImage
  HippoCanvasStyle      => StThemeNode

StThemeContext is a new class managing the theme for a stage and
global properties like resolution.

test-theme.c is a newly written test program to do verification of the
style matching and property handling rules.

Various changes are made in the import:

 - Comprehensive reindentation
 - guint32 pixels replaced with ClutterColor
 - General pseudo-class support added
 - Old-fashioned (non-bordered) background image support added, though
   with no support for repeat, etc.
 - Bug fixes for problems revealed by test program

83402957bb Add GObject Introspection annotations
Add GObject Introspection annotations to methods where needed, in
particular adding (transfer none) to return values that don't transfer
ownership.

st_texture_cache_get_actor() and st_texture_cache_get_texture()
are annotated as (transfer none) since they return a newly
created *floating* texture.

d291e568fd Import Mx core as ST
Import the core MxWidget/MxBin and their dependencies; we use the
namespace "St" (Shell Toolkit) because it is the same length as Mx
so enabling easy sharing of code, but makes it clear that this is
a friendly fork and not a literal import.

Based on a patch by Colin Walters <walters@verbum.org>
