+ * @property {number} [height=width] - The height of the grid in pixels.
+ * @property {number} [widthSegments=1] - The number of segments to split the grid horizontally in to.
+ * @property {number} [heightSegments=widthSegments] - The number of segments to split the grid vertically in to.
+ * @property {number} [x=0] - Offset the grid x position by this amount.
+ * @property {number} [y=0] - Offset the grid y position by this amount.
+ * @property {number|number[]} [colors=0xffffff] - An array of colors, one per vertex, or a single color value applied to all vertices.
