void parse(XmlElement rootElement)

Parses XML attributes to configure this area rendering instruction.

Processes XML attributes such as fill color, stroke properties, bitmap sources, display modes, and other styling parameters from the theme definition.

rootElement XML element containing the area instruction attributes
