730e8ffdf9 Add get_horizontal/vertical_padding() methods
Add get_horizontal_padding() and get_vertical_padding() methods,
that return the total padding (LEFT+RIGHT or TOP+BOTTOM).

3333f30c42 Convert border_width, border_radius to integers
This saves the consumers from having to deal with rounding.

721e1ea863 [St] Implement max-width/max-height in the CSS parser
st_theme_node_adjust_preferred_width/height now limit the content area
of an actor to the max, if given. (The requested width/height may be
larger to make room for borders, etc.)

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.

2dfe113a42 Implement -st-shadow for StWidget
Add support for a new -st-shadow property, which is based loosely
on the CSS3 box-shadow property:
http://www.css3.info/preview/box-shadow/

It defers from the specification as follows:

 * no multiple shadows
 * the optional color argument may be placed anywhere
 * the shape is not determined by the widget's bounding box,
   but by the background-image property

7b9f5b7643 Implement gradients for StWidget
Rather than having gradients be individually implemented by higher
level JS widgets, move basic gradient functionality into StWidget.
There is prior art in WebKit for CSS gradients:

http://webkit.org/blog/175/introducing-css-gradients/

However, implementing this would be quite a lot of work; all we
need in the Shell design at the moment is basic horizontal/vertical
linear gradients.  So, the syntax now supported is:

background-gradient-type: [vertical|horizontal]
background-gradient-start: color;
background-gradient-end: color;

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.

4d55ccff39 Rename StThemeImage to StBorderImage
The current CSS3 border-image is close to a superset of what we were
doing for -hippo-background-image. Woot! rename StThemeImage to
StBorderImage and change parsing to look for:

 border-image: <url> <number>...

Rather than

 -st-background-image: <url> <length>...

percentanges for the border sizes are not currently supported, neither
are the keywords for handling of the middle part. We always do 'stretch'
for now.

076e902b2c Centralize computations of border and padding into StThemeNode
Rather than repeating the computation of borders in many different
widget subclasses, add helper functions:

 st_theme_node_adjust_for_height()
 st_theme_node_adjust_preferred_width()
 st_theme_node_adjust_for_width()
 st_theme_node_adjust_preferred_height()
 st_theme_node_get_content_box()

That are used in get_preferred_width()/get_preferred_height() and
allocate() methods to consistently apply the necessary adjustments.
This allows removing the StPadding type.

Queueing a relayout when the borders/padding change is moved from
st_widget_real_style_changed() to the invoking code to allow access
to the old StThemeNode for comparison. (Should this be added as
a parameter to the signal?)

Borders are included in the geometry adjustments, but borders
are not yet drawn.

8c72623da3 StThemeNode: Add border-radius support

Different radii for the 4 corners are supported; elliptical corners
are not supported.

6527dbc8b7 Add support for inline styles
Add support for passing an inline-style string when creating a
StThemeNode.

Hook this up to a new 'style' property of StWidget.

Add a test case that demonstrates using this to update font sizes
on the fly.

276d9a9302 Import stylesheet code from hippo-canvas
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
