A method, apparatus, system, and signal-bearing medium that in an embodiment determines the visible regions of potentially overlapping views and writes the visible regions to an output device. The visible regions may be determined using the visible-above region associated with a view. The views may have child, parent, and sibling views. A view may be any object capable of being displayed. In this way, the number of times that a pixel is written to the output device is reduced.

Computing visible regions for a hierarchical view

Systems and methods for providing a user with increased flexibility and control over the appearance and behavior of objects on a user interface are described. Sets of objects can be grouped into themes to provide a user with a distinct overall impression of the interface. These themes can be invoked by calling a corresponding theme engine. Theme engines can be hard-coded or data-driven.
