Could you explain the use case a bit, I'm not sure I understand how this 
happens. First someone imports dmabufs, creating EGLImage. Then a 
texture is associated with that (glEGLImageTargetTexture2DOES?), is it 
so that then we create yet another EGLImage from that texture or am I 
completely lost here? :)
