1. A method implemented by a computing system that includes a processor and memory storing executable instructions for implementing the method, the method comprising: the computing system maintaining first data that identifies each driver of a class comprising one or more drivers; the computing system maintaining second data that identifies a window that is associated with the class; the computing system receiving graphics primitives associated with the window; and the computing system filtering the graphics primitives based on the first and second data to prevent the graphics primitives for the window from being sent to any driver of the class.
