Abstract
A software application and an operating system may run on a computer, which includes a graphics card and a video display, where the graphics card is operable to render images to the video display, and the operating system includes a universal application programming interface (API) which supports hardware layers on graphics cards. The operating system may be operable to receive draw events via the universal API; determine what hardware layers are available on the graphics card, and what their parameters are; and respond to draw requests from the software application by rendering the draw requests selectively to any of the available hardware layers on the graphics card.
