* \brief Simple implementation of EGL 1.3
* \note caveats:
- always renders into the backbuffer and blits it to window (no single buffered rendering)
- no native Windows or Mac OS X pixmap support
- no power management events
- no support for swap interval
* \todo what happens in egl functions when eglTerminate has been called but the context and surface are still in use?
* \todo OSDeinitMutex should be called in case getEGL fails.
