281b2e9b0e St: Fix blur radius computation to correspond to current CSS draft
The next draft of the CSS Backgrounds and Borders module will actually
define when the blur radius means. Fix our code to use that definition
(2 * standard deviation) rather than using the 1.9 * that we extracted
from what Mozilla was doing.

c58b8498b3 st: Add more error checking to shadow-related code
The additional error checks should catch quite some warnings (e.g.
when trying to create a shadow for a 0-width actor).

a3a6650e66 st-theme-node: Add support for inset box-shadows
Implement inset box-shadows as in the CSS3 draft[0]. As the shadow
should appear beneath the node's border, we pick the slow cairo based
rendering path (though a cogl based path could be added in case the
node has a solid background with no borders).

03757c1fcb st-private: add cairo code for drawing shadow
This does the same thing as the cogl equivalent
code, but for handling fallbacks.

1faee65a68 st-private: split pixel blurring code out
The guts are somewhat complicated, and
are potentially reusable for future cairo
fallback code.

8dcd70edbe St: Use clutter_actor_get_request_mode
Use clutter_actor_get_request_mode rather than g_object_get
since we have it in the required clutter version.

ce72aaf008 Fix up copyright and license notices for St
* Make sure all source files have a LGPL copyright header, and standardize
  non-standard variations of the header to a common form.

* Check and update all copyright notices.

* Remove 'Written By:' lines. They are universally incomplete and
  typically indicate only who started a particular file.

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.

1034798969 st-shadows: Use a template material when creating shadows
To avoid recompiling shadows each time a new shadow is created,
use a copy of a static template material.

ba1da9deb9 [StThemeNode] Make shadow helper functions semi-public
Move shadow helper functions from st-theme-node-drawing to st-private
to make them available to widgets which want to add shadows to internal
actors.
Also add a new helper function for creating the shadow material from a
ClutterActor.

766b5b801c [St] Remove _st_actor_contains()
The function has been upstreamed as clutter_actor_contains() - with
the switch to clutter-1.4 it is now available to the Shell, so it
is no longer necessary to keep a copy in-tree.

97f883b10e Implement "text-align"
"text-align" allows setting the alignment of text, with respect to
other lines and allocated space, without requiring a reference to
the ClutterText (which is private for most widgets).
If not specified, all text is left-aligned.

a4befeba53 De-duplicate "actor contains actor" code
Add _st_actor_contains() in st-private for use within St, and
monkey-patch in a Clutter.Actor.contains() for use by javascript, and
then replace all the duplicate implementations with one or the other
of those.

74ccdbf3a9 St: fix allocation to not use both wfh and hfw
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.

54d11b65a1 Move shared container methods from st-private to a common base class
Add StContainer, which implements the ClutterContainer interface based
on the container methods in st-private and make the existing containers
subclass it.

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
nearly-identical duplicate copies of the code.

55fbb9d0af [St] Implement text-decoration: [underline|strikethrough]
Move CSS handling of StLabel and StButton for their underlying
ClutterText objects into st_private, and implement support for
the underline and strikethrough St text-decoration properties.

Overline isn't implemented for lack of a corresponding Pango
attribute, and blink, well...

e91e8e993d Add emacs mode-lines to ST sources
To each .c and .h file, add:

 /* -*- mode: C; c-file-style: "gnu"; indent-tabs-mode: nil; -*- */

'gnu' is the default anyways for Emacs, but indent-tabs-mode is not,
so this sets things up to correspond to the policy of no-tabs.

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.
