I think that would be a reasonable extension to TextureMapperGL and I think we need it anyway (despite being SoC/GPU specific). Of course the GStreamer interface doesn't specify anything there right now, so I think it will require some extensions. Perhaps as simple as the GstSurfaceConverter implementation providing a function for compiling the fragment shader needed for rendering the texture.
