Applications use the target hardware's GPU to perform rendering operations with Khronos rendering API calls, or
use blitting with the native Screen API function calls.
Khronos rendering APIs Screen supports the following Khronos rendering APIs: OpenGL ES and OpenVG. They provide common interfaces to graphics hardware that allow users to generate and manipulate high quality graphics images of two-dimensional vector and three-dimensional graphics.
Blitting Screen provides native rendering APIs that use the hardware blitter to move data from one area of memory to another without involving the CPU.
