Cut down on boilerplate by using the (no longer that) new helper
macros. We don't care about breaking ABI in private libraries, so
use G_DECLARE_FINAL_TYPE even where the class struct used to be
exposed in the header, except for types we inherit from ourselves
(obviously) or where the class exposes any vfuncs (where changes
could affect inheritance in extensions).
Because we calculate and cache CSS properties once per StThemeNode,
and only a certain set of attributes can affect the CSS properties,
it's advantageous for as many widgets as possible to share a single
StThemeNode. Similarly, if a widget changes state and then changes back
(e.g. gaining and losing the :hover pseudo-class), it should ideally
get its original StThemeNode back again when it returns to the old
state.
Here, I'm using the StThemeContext as the location for a cache.
StThemeNodes are currently never freed: this seems OK for Shell's usage
(a finite number of IDs, classes, pseudo-classes and types).

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
