Class Description

                                                                      
 TGColorPalette, TGColorPick and TGColorDialog.                       
                                                                      
 The TGColorPalette is a widget showing an matrix of color cells. The 
 colors can be set and selected.                                      
                                                                      
 The TGColorPick is a widget which allows a color to be picked from   
 HLS space. It consists of two elements: a color map window from      
 where the user can select the hue and saturation level of a color,   
 and a slider to select color's lightness.                            
                                                                      
 Selecting a color in these two widgets will generate the event:      
 kC_COLORSEL, kCOL_CLICK, widget id, 0.                               
 and the signal:                                                      
 ColorSelected(ULong_t pixel)                                         
                                                                      
 The TGColorDialog presents a full featured color selection dialog.   
 It uses 2 TGColorPalette's and the TGColorPick widgets.

TGColorPalette(const TGWindow *p, Int_t cols, Int_t rows, Int_t id) : TGFrame(p, 10, 10, kChildFrame), fDrawGC(TGButton::GetDefaultGC())

 TGColorPalette widget: this is just a grid of color cells of the
 specified size. Colors can be selected by clicking on them or by
 using the arrow keys.
