		// near mEglHelper.swap() in GLSurfaceView while processing next onPause event.
		// See related issue:
		// http://code.google.com/p/libgdx/issues/detail?id=541
		// the problem with graphics.pause occurs while using OpenGL 2.0 and original GLSurfaceView while rotating device
		// in lwp preview
		// in my opinion it is a bug of android not libgdx, even example Cubic live wallpaper from
		// Android SDK crashes on affected devices.......... and on some configurations of android emulator too.

		// My wallpaper was rejected on Samsung Apps because of this issue, so I decided to disable graphics.pause..
