EGL

1. EGL(Embedded-system Graphics Library)

- was OpenGL ES Native Platform Graphics Interface before ver 1.2

- an interface between rendering APIs such as OpenGL or OpenVG(client APIs) and an underling native platform window system.

- handles graphics context management, surface/buffer binding, and rendering synchronization and enables "high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs.

- is intended to be implementable on multiple operating systems (such as Symbian,

embedded Linux, Unix, and Windows) and native window systems (such as

X and Microsoft Windows).

- is to provide a means to create client API rendering contexts

(henceforth simply referred to as contexts), and associate them with drawing

surfaces.
