Class Description

*-*-*-*-*-*-*-*-*-*-*-*-*Line Attributes class*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      =====================
*-*  Line attributes are:
*-*    Line Color (see TAttFill for the list of colors)
*-*    Line Style 1=solid, 2=dash, 3=dot-dot, 4=dash-dot
*-*    Line Width expressed in pixel units
*-*
*-*  This class is used (in general by secondary inheritance)
*-*  by many other classes (graphics, histograms).

*-*-*-*-*-*-*-*-*-*-*-*-*AttLine default constructor*-*-*-*-*-*-*-*-*-*-*-*
*-*                      ===========================
*-*  Default line attributes are taking from the current style
*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

*-*-*-*-*-*-*-*-*-*-*-*-*AttLine normal constructor*-*-*-*-*-*-*-*-*-*-*-*
*-*                      ===========================
*-*  Line attributes are taking from the argument list
*-*    color : must be one of the valid color index
*-*    style : 1=solid, 2=dash, 3=dash-dot, 4=dot-dot
*-*    width : expressed in pixel units
*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*

*-*-*-*-*-*-*-*-*-*-*-*-*AttLine destructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      =================

*-*-*-*-*-*-*-*-*Copy this line attributes to a new attline*-*-*-*-*-*-*-*-*
*-*              ==========================================

*-*-*-*-*-*-*-*-*-*-*Compute distance from point px,py to a line*-*-*-*-*-*
*-*                  ===========================================
*-*  Compute the closest distance of approach from point px,py to this line.
*-*  The distance is computed in pixels units.
*-*
*-*  Algorithm:
*-*
*-*    A(x1,y1)         P                             B(x2,y2)
*-*    ------------------------------------------------
*-*                     I
*-*                     I
*-*                     I
*-*                     I
*-*                    M(x,y)
*-*
*-*  Let us call  a = distance AM     A=a**2
*-*               b = distance BM     B=b**2
*-*               c = distance AB     C=c**2
*-*               d = distance PM     D=d**2
*-*               u = distance AP     U=u**2
*-*               v = distance BP     V=v**2     c = u + v
*-*
*-*  D = A - U
*-*  D = B - V  = B -(c-u)**2
*-*     ==> u = (A -B +C)/2c
*-*
