    摘要: A display mixer exports a first set of functions adapted to be called by one or more object libraries to create one or more generic objects. A surface/attribute manager exports a second set of functions adapted to be called by an application to manipulate the generic objects. The display mixer and the surface/attribute manager cause the generic objects to be rendered into a common draw surface. The display mixer and the surface/attribute manager manage a set of common attributes shared by the generic objects and manage attachments between the generic objects. A first object library calls a create-object function in the display mixer to create one or more first generic objects. The first object library generates display data for the first generic objects and the display mixer coordinates the display of the display data for the first generic objects.
