Code example for EGLContext

Methods: getGL

			 * Before we can issue GL commands, we need to make sure  
			 * the context is current and bound to a surface. 
			egl.eglMakeCurrent(dpy, surface, surface, context);
			 * Get to the appropriate GL interface. 
			 * This is simply done by casting the GL context to either 
			 * GL10 or GL11. 
			gl = (GL10)context.getGL();
			 * By default, OpenGL enables features that improve quality 
			 * but reduce performance. One might want to tweak that 
			 * especially on software renderer.
