The texture bounds attribute is useful for example when rendering geometry that uses a shared texture atlas; one can store the individual texture bounds in the vertex data and use normalized (0,1) UV coordinates, which a shader will then convert to coordinates on the atlas. This also allows repeating UV patterns by applying wrapping in the shader.
