This component is suitable for backgrounds and grouping other elements. Note that because it has a single repeating material it cannot have a discrete border (unless the texture has one and the texture is tiled only once). For a bordered panel, see it's subclass BorderPanel.
Note that the material can have all the usual effects applied to it like multiple texture layers, scrolling / animated textures etc. For multiple texture layers, you have to set the tiling level for each layer.
