/**
* @classdesc
* The ScaleManager object handles the the scaling, resizing, and alignment of the
* Game size and the game Display canvas.
*
* The Game size is the logical size of the game; the Display canvas has size as an HTML element.
*
* The calculations of these are heavily influenced by the bounding Parent size which is the computed
* dimensions of the Display canvas's Parent container/element - the _effective CSS rules of the
* canvas's Parent element play an important role_ in the operation of the ScaleManager.
*
* The Display canvas - or Game size, depending {@link #scaleMode} - is updated to best utilize the Parent size.
* When in Fullscreen mode or with {@link #parentIsWindow} the Parent size is that of the visual viewport (see {@link Phaser.ScaleManager#getParentBounds getParentBounds}).
*
* Parent and Display canvas containment guidelines:
*
* - Style the Parent element (of the game canvas) to control the Parent size and
* thus the Display canvas's size and layout.
*
* - The Parent element's CSS styles should _effectively_ apply maximum (and minimum) bounding behavior.
*
* - The Parent element should _not_ apply a padding as this is not accounted for.
* If a padding is required apply it to the Parent's parent or apply a margin to the Parent.
* If you need to add a border, margin or any other CSS around your game container, then use a parent element and
* apply the CSS to this instead, otherwise you'll be constantly resizing the shape of the game container.
*
* - The Display canvas layout CSS styles (i.e. margins, size) should not be altered/specified as
* they may be updated by the ScaleManager.
*
* @description
* Create a new ScaleManager object - this is done automatically by {@link Phaser.Game}
*
* The `width` and `height` constructor parameters can either be a number which represents pixels or a string that represents a percentage: e.g. `800` (for 800 pixels) or `"80%"` for 80%.
*
* @class
* @param {Phaser.Game} game - A reference to the currently running game.
* @param {number|string} width - The width of the game. See above.
* @param {number|string} height - The height of the game. See above.
