ROOT does not use exceptions, so, if default painter's creation failed,
fDefaultPainter is 0. In each function, which use it, I have to check pointer first.

Selects plot or axis.
9999 is the magic number, ROOT's classes use in DistancetoPrimitive.

Default implementation is OK.

 Execute event.

Default implementation is OK.

 Get contour list.

Overrides TObject::GetObjectInfo.
Displays the histogram info (bin number, contents, integral up to bin
corresponding to cursor position px,py.

 Get stack.

Returns kTRUE if the cell ix, iy is inside one of the graphical cuts.

Returns kTRUE if the cell x, y is inside one of the graphical cuts.

 Paint statistics.

 Process message.

 Set histogram.

 Set stack.

 Make cuts.

Final-overrider for TObject::Paint.

In principle, we can have several conflicting options: "lego surf pol sph",
but only one will be selected, which one - depends on parsing order in this function.

 Create painter.

 Set show projection.
