----------------------------------------------------------------------


pst-eucl.pro --------
1.04 2020/09/29     
  - some new functions for 1.75


pst-eucl.tex --------
1.75  2020/09/29 
  - add macro to calc the coefficents of general conic $ax^2+bxy+cy^2+dx+ey+f=0$ through given five points, \pstGeneralConicEquation.
  - add macro to calc the coefficents of general conic $ax^2+bxy+cy^2+dx+ey+f=0$ of the given ellipse, \pstGeneralEllipseEquation.
  - add macro to calc the coefficents of general conic $ax^2+bxy+cy^2+dx+ey+f=0$ of the given hyperbola, \pstGeneralHyperbolaEquation.
  - add macro to calc the coefficents of general conic $ax^2+bxy+cy^2+dx+ey+f=0$ of the given parabola, \pstGeneralParabolaEquation.
  - add macro to draw the intersections of line AB and general conic $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicLineInter.
  - add macro to draw the intersections of circle OA and general conic $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicCircleInter.
  - add macro to draw the intersections of ellipse and general conic $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicEllipseInter.
  - add macro to draw the intersections of hyperbola and general conic $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicHyperbolaInter.
  - add macro to draw the intersections of parabola and general conic $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicParabolaInter.
  - add macro to draw the intersections of two general conics $ax^2+bxy+cy^2+dx+ey+f=0$, \pstGeneralConicInter.
  - fix an issue in \pstGeneralHyperbolaCoef that it gets the wrong symmetrical axis when draw quadratic curve 2xy-x+2y+1=0.
  - update \pstGeneralHyperbolaABCDE to support the quadratic curve equation with a=0, e.g, given five points from curve xy=1.  
  - update the (pos) parameter U|D|L|R to :U|:D|:L|:R in \pstTriangleSSS, \pstTriangleSAS etc, 
                       and support (node) to specify a base line to draw the triangle.
