Use of tfractionfitter with 2-di histos

Hi, is it possible to fit two-di histos with TFractionFitter ?
The documentation is ambiguous. By one side, the creator seems only to take TH1* as input, on the other side there are several references here and there to two and also three-di fits.
If it is possible, where can I find an example ?

it should work also for 2D (or 3D) histograms. There are no examples for this case, but everything should be the same, just pass to the class the 2D histograms.
