Instead of using "Monospace", pick the users configured monospace font
name up from GConf. (This is a nice touch, but is more done here to
demonstrate that we can do it rather than for any great utility.)
* Style aspects like colors and fonts are moved into gnome-shell.css.
* Scrolling is adding using NbtkScrollView.
Based on a patch from Colin Walters
https://bugzilla.gnome.org/show_bug.cgi?id=591245
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.
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.)
