Abstract
In general, one aspect of the subject matter described in this specification can be embodied in a method for providing a hierarchical data structure to store nodes, wherein the nodes comprise graphical primitives to be rendered to a common display space of a computer system. The hierarchical data structure governs graphical compositing amongst the nodes. Two or more separate software applications are allowed to create nodes in the hierarchical data structure and share the common display space. The two or more separate software applications are restricted from accessing nodes in the hierarchical data structure based on node ownership information linking one or more nodes in the hierarchical data structure to a respective software application in the two or more separate software applications. The hierarchical data structure is used for rendering and displaying the common display space.
