* @short_description: style information for one node in a tree of themed objects
14
* A #StThemeNode represents the CSS style information (the set of CSS properties) for one
15
* node in a tree of themed objects. In typical usage, it represents the style information
16
* for a single #ClutterActor. A #StThemeNode is immutable: attributes such as the
17
* CSS classes for the node are passed in at construction. If the attributes of the node
18
* or any parent node change, the node should be discarded and a new node created.
19
* #StThemeNode has generic accessors to look up properties by name and specific
20
* accessors for standard CSS properties that add caching and handling of various
21
* details of the CSS specification. #StThemeNode also has convenience functions to help
22
* in implementing a #ClutterActor with borders and padding.
