Havn't tested just checked the code, so i might be wrong but this function:

function Backdrop:BorderTextureFunction(func,...)
    -- check to see the function exists for a texture object
    if not self._backdrop.bgTexture[func] then return end
    for point, texture in pairs(frame._backdrop.edgeTextures) do
        texture[func](texture,...)
    end
end

Shouldn't have "self._backdrop.edgeTextures" instead of "frame._backdrop.edgeTextures"?
