Quadratic Curve - can be reoriented - CANNOT DETECT ENTRY/EXIT in curves, even when filled (they look as, but are not, closed shapes)
a quadratic curve is a curved segment that has two endpoints and one control point. The control point determines the shape of the curve by controlling both of the endpoint tangent vectors
for this particular glyph, vx and vy correspond to the center of the imaginary segment linking the curve's start and end points
the coordinates of the control point are expressed w.r.t this point in polar coordinates (orient=0 on segment linking start and end points, meaning that if orient=0, start control and end points are aligned)

Field Summary
(package private)  float ang
           
(package private)  ProjQdCurve[] pc
          array of projected coordinates - index of camera in virtual space is equal to index of projected coords in this array
(package private)  long vrad
          control point, polar coordinates - origin is vx,vy - orient=0 on segment linking start and end points
(package private)  long vs
          size (distance between start and end point)

Method Summary
 void addCamera(int verifIndex)

          detects whether the given point is inside this glyph or not

          draw glyph
 boolean fillsView(long w, long h, int camIndex)
          used to find out if glyph completely fills the view (in which case it is not necessary to repaint objects at a lower altitude)
 float getCtrlPointAngle()
          get orientation of control point (polar coords)
 long getCtrlPointRadius()
          get distance from center of segment linking start and end points to control point (polar coords)
 float getOrient()
          get orientation
 float getSize()
          get size (bounding circle radius)
 void initCams(int nbCam)
          called when glyph is created in order to create the initial set of projected coordinates wrt the number of cameras in the space
 int mouseInOut(int x, int y, int camIndex)
          returns 1 if mouse has entered the glyph, -1 if it has exited the glyph, 0 if nothing has changed (meaning it was already inside or outside it)
 void orientTo(float angle)
          set orientation (absolute)
 void project(com.xerox.VTM.engine.Camera c, com.xerox.VTM.engine.ViewPanel v)
          project shape in camera coord sys prior to actual painting
 void removeCamera(int index)
          if a camera is removed from the virtual space, we should delete the corresponding projected coordinates, but do not modify the array it self because we do not want to change other cameras' index - just point to null
 void resetMouseIn(int i)
          reset prevMouseIn for projected coordinates nb i
 void reSize(float factor)
          multiply bounding circle radius by factor
 void setCtrlPoint(long d, float o)
          set position of control point (polar coords w.r.t center of segment linking start and end points)
 void sizeTo(float radius)
          set absolute size by setting bounding circle radius
(package private)  void textDraw(java.awt.Graphics2D g, int i)
          draw text associated with this glyph
