[ROOT] fitting TGraphErrors object

Hello,

 I notice that TGraphErrors does not override the TGraph::Fit().  Does this
mean that TGraphErrors::Fit() does not know about a TGraphError object's
y-errors?   Is there an (easy) way to fit points (x_i, y_i, e_i) to a
function y=f(x) where e_i is measurement error on y_i?  Thanks.
