示例1: PaintNoSpaceAfterPeriod

{

g = RichText.CreateGraphics ();
//Pen myPen = null;// new Pen (Color.FromArgb (60, Color.Yellow)); // Alpha did not seem to work this way
// this gets tricky. The loop is just to find all the [[~scenes]] on the note
// even if offscreen.
// OK: but with th eoptimization to only show on screen stuff, do we need this anymore???
