I wonder if there is an easy way to project a TF2 to TF1, by fixing either
x or y? I searched the ROOTtalk site and went through the document, but
could not find it. Basically, I would like to have something like, for
example:

TF2 *f2 = new TF2("f2", "x*y/([0]**2+x**2+y**2)",-10,10,-10,10, 1);
TF1 *f1 = f2->ProjectionX("_px", -1);  // i.e. y=-1.0

Is it easy to implement something like that?
