Last Point yellow

Added a clear first point distinction when drawing a custom shape: if the mouse cursor is near the beginning of a line (the shape can be closed), the first point is drawn in yellow and larger. This allows the user to see when they can close the shape with a single click. The code has been compiled and is ready to use. The functionality works as expected.
