NbtkBoxLayout: Make consistent that the area scrolled and clipped
to is the content area (excluding borders and padding.) Translate
back appropriately when chaining up so that the parent background
is drawn at the right place and picking on the box (if it's reactive)
picks at the right place on the screen.
clip-to-allocation is removed from NbtkScrollView since it's just
not right - if the child has any non-moving elements, like headers or
borders, it will need to set a narrower clip. And even if the entire
child scrolls, we want to clip to an arrow that excludes the scrollbars.
When a NbtkBoxLayout 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 CSS specification says that the background extends to the
edge of the border (settable in CSS3 with border-clip), make
BigRectangle match this by computing an "effective border color"
as 'border OVER background'.
(If we don't want this behavior - e.g., to be able to use the
transparent borders as margins, then alternatively transparent
border handling would have to be fixed in nbtk-widget.c, since
prior to this transparent and translucent borders were handled
differently.)
The current CSS3 border-image is close to a superset of what we were
doing for -hippo-background-image. Woot! rename ShellThemeImage to
ShellBorderImage and change parsing to look for:
border-image: <url> <number>...
Rather than
-shell-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.
Use BigRectangle to draw the border and background if there's
a border width or border radius and no border image. (Only
uniform borders are supported for now with some deviations
from the CSS model noted in the comments.)
The background color and image parameters are removed from
NbtkWidget's draw_background() method since they were not used
for NbtkButton (the only current user) and the encapsulation
break that they presented caused some minor problems.
Add a test case for borders, and also use borders to style
the buttons in the 'inline-style' test case.
Add support for passing an inline-style string when creating a
ShellThemeNode.
Hook this up to a new 'style' property of NbtkWidget.
Add a test case that demonstrates using this to update font sizes
on the fly.
ShellTheme replaces both NbtkStyle and ccss_stylesheet_t.
The interface NbtkStylable 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 NbtkStylable and ccss_node_t.
Some operations that were previously on NbtkStylable (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.
Install and distribute gnome-shell.css and theme images. They are moved
down from $datadir to $datadir/theme to avoid a weirdness where we have
images in $datadir and then also in $datadir/images.
(Also moved in the source tree to avoid adding another difference between
installed and uninstalled operation.)
