Adding transparency support?

Ah, never mind I got it working. I think it was the depth buffer getting in the way, so I disabled it.

I'll tidy this up and make a PR.

Hi~ May I ask you how to render a picture with a transparent background? All my results are like:

I know I should adjust the background_attributes, but I do not know how to set it.

pixels = dirt.rasterise_deferred(
        vertices=cube_vertices_clip,
        vertex_attributes=tf.concat([
            tf.ones_like(cube_vertices_object[:, :1]),  # mask
            cube_uvs,  # texture coordinates
            cube_normals_world  # normals
        ], axis=1),
        faces=cube_faces,
        background_attributes=(tf.ones([frame_height, frame_width, 6])*255),
        shader_fn=shader_fn,
        shader_additional_inputs=[texture, light_direction]
    )

Thanks for any help and guidance!
Best,
Frank
