    cogl-pango-display-list: Don't use VBOs if the texture can't handle it
    
    If the texture can't be hardware repeated (ie, if it is sliced or it
    has waste) then Cogl will reject the layer when rendering with a
    VBO. In this case we should always fall back to rendering with
    cogl_rectangle.
