Please fix the following reader-reported issues:

1. Class Rectangle


Rectangle(double x, double y, double width, double height)
Creates a new instance of Rectangle with the given position, size and fill.
 
Issue: there is no argument for fill in this constractor.

2. Class Node

    java.lang.Object
        javafx.scene.Node

 
visible
Specifies whether this Node and any subnodes should be rendered as part of the scene graph. A node may be visible and yet not be shown in the rendered scene if, for instance, it is off the screen or obscured by another Node. Invisible nodes never receive mouse events or keyboard focus, and never maintain keyboard focus when they become invisible.

Issue: incorrect punctuation in the second sentence.
