//*-*-*-*-*-*-*-*-*-*-*-*-*Fill Area Attributes class*-*-*-*-*-*-*-*-*-*-*-*
//*-*                      ==========================
//*-*  Fill Area attributes are:
//*-*    Fill Color
//*-*    Fill Style
//*-*
//*-*  This class is used (in general by secondary inheritance)
//*-*  by many other classes (graphics, histograms).
//*-*
//*-*  The following table shows the list of default colors.
//
/*

//
//
//  Conventions for fill styles:
//    0    : hollow
//    1001 : Solid
//    2001 : hatch style
//    3000+pattern_number (see below)
//    4000 :the window is transparent.
//    4000 to 4100 the window is 100% transparent to 100% opaque
//
//*-*  The following table shows the list of pattern styles.
