Picture: Add methods getWidth, getHeight.

[capdevon]

The Pictureclass has the setter methods on the widthand heightattributes, but there are no getter methods. Would you please add them? They would come in handy. Thank you.

public class Picture extends Geometry {

    private float width  = 1f;
    private float height = 1f;

    // -----------------------------------------------
    // >>> The getter methods are missing <<<
    // -----------------------------------------------
    [...]

    /**
     * Set the width in pixels of the picture, if the width
     * does not match the texture's width, then the texture will
     * be scaled to fit the picture.
     * 
     * @param width the width to set.
     */
    public void setWidth(float width){
        this.width = width;
        setLocalScale(new Vector3f(width, height, 1f));
    }

    /**
     * Set the height in pixels of the picture, if the height
     * does not match the texture's height, then the texture will
     * be scaled to fit the picture.
     * 
     * @param height the height to set.
     */
    public void setHeight(float height){
        this.height = height;
        setLocalScale(new Vector3f(width, height, 1f));
    }

}

Good idea. I'll implement the methods.
