Class Description

 a PAVE is a TBox with a bordersize and a shadow option
 The corners of a TPave can be rounded (option "arc")
 More functional objects like TPavelabel, TPaveText derive from TPave.

TPave(): TBox()
*-*-*-*-*-*-*-*-*-*-*pave default constructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  ========================

TPave(Double_t x1, Double_t y1,Double_t x2, Double_t y2, Int_t bordersize ,Option_t *option) :TBox(x1,y1,x2,y2)
*-*-*-*-*-*-*-*-*-*-*pave normal constructor*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                  =======================
 a PAVE is a box with a bordersize and a shadow option
 the bordersize is in pixels
  option = "T" Top frame
  option = "B" Bottom frame
  option = "R" Right frame
  option = "L" Left frame
  option = "NDC" x1,y1,x2,y2 are given in NDC
  option = "ARC" corners are rounded

  IMPORTANT NOTE:
  Because TPave objects (and objects deriving from TPave) have their
  master coordinate system in NDC, one cannot use the TBox functions
  SetX1,SetY1,SetX2,SetY2 to change the corner coordinates. One should use
  instead SetX1NDC, SetY1NDC, SetX2NDC, SetY2NDC.

  option = "NDC" x1,y1,x2,y2 are given in NDC
  option = "ARC" corners are rounded
      In case of option "ARC", the corner radius is specified
      via TPave::SetCornerRadius(rad) where rad is given in percent
      of the pave height (default value is 0.2).
