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).
