F4.6} Projection

 The projection frame allows the user to quickly and accurately
 place the location, zoom, orientation of the viewport as well
 to save and recall (bookmark) locations in the geometry

        

 The dialog shows/hides with the  has the following tabs
 Press <Return> or the  to apply the change

 [Origin]  move the center of the viewport to
       x:   center of viewport
       y:        -//-
       z:        -//-

 [Extends]   zoom viewport by setting the Du extends
      Du:   half width of the horizontal axis
      Dv:   half height of the vertical axis (Read-only)

   [Move]   move relative to current projection the center by
      +u:   along the u (horizontal axis)
      +v:   along the v (vertical axis)
      +w:   along the w (towards the viewer axis)

  [Basis]   quickly set the axis-basis of the plot
 ux,uy,uz:   u vector components.
            Note: it doesn't have to be normalized to 1.0
 vx,vy,vz:   v vector components
      x-y,  z-x,  z-y
      swap  swap orientation u <-> v
      -u    inverse u
      -v    inverse v

  [Euler]   define the orientation by entering the Euler rotations
      Rx:   rotation in X axis
      Ry:   rotation in Y axis
      Rz:   rotation in Z axis
      The order of rotation is Rz -> Ry -> Rx

 [Rotate]   rotate relative to current viewport
      Ru:   rotation along u axis
      Rv:   rotation along v axis
      Rw:   rotation along w axis
      The order of rotation is Rw -> Rv -> Ru

 [Transform] transform current viewport with the following ROT-DEFI
  Rotdefi:  roto-translation (normal or inverse)
            Selecting a LATTICE region the Rotdefi is
            automatically selected

 [Bookmarks] save/recall geometry views
     Plot:  all saved views are stored as Geometry plots in flair
      :   add a new bookmark
      :   delete currently selected one
      :  save the present location to the selected
             bookmark
      :   apply the bookmark

   Note: the first field x, Du, ux, vx, Rx, Ru accepts either
   * Numerical value
   * Vector with 2 or 3 values to substitute on the other fields
     e.g Entering on "X:" the value  "10.0 50.0 -100.0"
         Will set on X:10.0,  on Y:50.0 and on Z:-100.0
     It can be practical when you want to copy paste the values
