EGL/OpenGL api do not directly support this... Instead the OpenMAX
specification itself states how to handle the interaction between Egl,
OpenGL ES, and OpenVG.

Document: OpenMAX IL 1.1.2 Specification
Download Location: http://www.khronos.org/registry/omxil/
Section 3.2: OpenMAX IL Core Methods/Macros ( Page 78 to 111 )
Subsection 3.2.2.19 OMX_UseEGLImage ( Page 102 to 104 )
This section itself is the critical section to look at.

Section 3.3: OpenMAX IL Component Methods and Structures ( Page 111 to 118 )
subsection 3.3.19 UseEGLImage ( Page 118 )
Not a lot is said, Just provides a definition for UseEGLImageBuffer and
redirects to the previously mentioned section.
