Why the rect created in the canvas doesn't follow the width n height stated?
this.canvas = {
            innerElement: TBE.CreateRectCanvasElement (Element.config.displayWidth, Element.config.displayHeight)
        };
    this.canvas.innerElement.style.border = '1px solid black';
    this.innerElementCtx = this.canvas.innerElement.getContext("2d");
    this.innerElementCtx.fillStyle = '#3ac6e5';
    this.innerElementCtx.fillRect(50, 50, 100, 100);
