[clutter/wip/pango-share-atlas: 2/14] cogl-pango-display-list: Don't use VBOs if the texture can't handle it

    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.
    
    This commit is only needed temporarily because Cogl will end up
    putting atlas textures in the display list. A later commit in the
    series will make it so that the display list always has primitive
    textures in it so this commit can be reverted.
