Creates a new [[docs/widgets/Texture`Texture`]] as a child of the frame.
Creates a new Texture as a child of the frame. The sublevel argument can be used to provide layering of textures within a draw layer. As it can be difficult to compute the proper layering, addon authors should avoid using this option, and it's XML equivalent textureSubLevel without reason. It should also be noted that FontStrings will always appear on top of all textures in a given draw layer.
