 Constructor.
This plot always needs a palette.

Show box info (i, j, k, binContent).

Set ranges, find min and max bin content.

 User clicks right mouse button (in a pad).

void Pan(Int_t px, Int_t py)

 User's moving mouse cursor, with middle mouse button pressed (for pad).
 Calculate 3d shift related to 2d mouse movement.

void AddOption(const TString& stringOption)

 "z" draw palette or not.

 Remove sections, switch on/off box cut.

void InitGL() const

 Initialize some gl state variables.

void DeInitGL() const

 Return back some gl state variables.

void DrawPlot() const

 Draw "voxels".

void DrawSectionXOZ() const

 Noop.

void DrawSectionYOZ() const

 Noop.

void DrawSectionXOY() const

 Noop.

void DrawPalette() const

Draw. Palette.

Draw. Palette. Axis.

void PreparePalette() const

Generate palette.

void FindVoxelColor(Double_t binContent, Float_t* rgba) const

 Find box color.

void SetVoxelColor(const Float_t* rgba) const

 Set box color.
