    摘要： Described is a pluggable policy component that determines the look and feel, or windows visual experience, of a computer user interface. Window-related instructions are redirected to the policy component, while client area change instructions are provided to a substrate (into which the policy component plugs in) that includes a composition component. The plug-in policy component handles windows-related (e.g., structural or attribute) changes to a scene graph to construct and maintain the scene graph, while the substrate handles program content changes to the client areas within windows. The substrate may include a desktop window manager that has access to the client areas in the scene graph, whereby the desktop window manager can copy a client area for rendering. For example, the desktop window manager can provide a supplemental live thumbnail image of a window.

    摘要： A visual tree structure as specified by a program is constructed and maintained by a visual system's user interface thread. As needed, the tree structure is traversed on the UI thread, with changes compiled into change queues. A secondary rendering thread that handles animation and graphical composition takes the content from the change queues, to construct and maintain a condensed visual tree. Static visual subtrees are collapsed, leaving a condensed tree with only animated attributes such as transforms as parent nodes, such that animation data is managed on the secondary thread, with references into the visual tree. When run, the rendering thread processes the change queues, applies changes to the condensed trees, and updates the structure of the animation list as necessary by resampling animated values at their new times. Content in the condensed visual tree is then rendered and composed. Animation and a composition communication protocol are also provided.
