/**
 * A Text Object will create a line or multiple lines of text.
 *
 * The text is created using the [Canvas API](https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API).
 *
 * The primary advantage of this class over BitmapText is that you have great control over the style of the text,
 * which you can change at runtime.
 *
 * The primary disadvantages is that each piece of text has it's own texture, which can use more memory.
 * When text changes, this texture has to be re-generated and re-uploaded to the GPU, taking up time.
 *
 * To split a line you can use '\n' in your text string, or, on the `style` object,
 * change its `wordWrap` property to true and and give the `wordWrapWidth` property a value.
 *
 * A Text can be created directly from a string and a style object,
 * which can be generated [here](https://pixijs.io/pixi-text-style).
 *
 * ```js
 * let text = new PIXI.Text('This is a PixiJS text',{fontFamily : 'Arial', fontSize: 24, fill : 0xff1010, align : 'center'});
