ScaleManager
</h2>
<div class="class-description"><p>The ScaleManager object handles the the scaling, resizing, and alignment of the
Game size and the game Display canvas.</p>
<p>The Game size is the logical size of the game; the Display canvas has size as an HTML element.</p>
<p>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 <em>effective CSS rules of the
canvas's Parent element play an important role</em> in the operation of the ScaleManager. </p>
<p>The Display canvas - or Game size, depending <a href="Phaser.ScaleManager.html#scaleMode">scaleMode</a> - is updated to best utilize the Parent size.
When in Fullscreen mode or with <a href="Phaser.ScaleManager.html#parentIsWindow">parentIsWindow</a> the Parent size is that of the visual viewport (see <a href="Phaser.ScaleManager.html#getParentBounds">getParentBounds</a>).</p>
<p>Parent and Display canvas containment guidelines:</p>
<ul>
<li><p>Style the Parent element (of the game canvas) to control the Parent size and
thus the Display canvas's size and layout.</p>
</li>
<li><p>The Parent element's CSS styles should <em>effectively</em> apply maximum (and minimum) bounding behavior.</p>
</li>
<li><p>The Parent element should <em>not</em> 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.</p>
</li>
<li><p>The Display canvas layout CSS styles (i.e. margins, size) should not be altered/specified as
they may be updated by the ScaleManager.</p>
</li>

<p>When enabled the Display canvas will be vertically-aligned <em>in the Parent container</em> (or <a href="Phaser.ScaleManager.html#parentIsWindow">window</a>).</p>
<p>To align vertically the Parent element should have a <em>non-collapsible</em> height, such that it will maintain
a height <em>larger</em> than the height of the contained Game canvas - the game canvas will then be scaled vertically
<em>within</em> the remaining available height dictated by the Parent element.</p>
<p>One way to prevent the parent from collapsing is to add an absolute &quot;min-height&quot; CSS property to the parent element.
If specifying a relative &quot;min-height/height&quot; or adjusting margins, the Parent height must still be non-collapsible (see note).</p>
<p><em>Note</em>: In version 2.2 the minimum document height is <em>not</em> automatically set to the viewport/window height.
To automatically update the minimum document height set <a href="Phaser.ScaleManager.html#compatibility">compatibility.forceMinimumDocumentHeight</a> to true.</p>

<p>The &quot;refresh&quot; methods informs the ScaleManager that a layout refresh is required.</p>
<p>The ScaleManager automatically queues a layout refresh (eg. updates the Game size or Display canvas layout)
when the browser is resized, the orientation changes, or when there is a detected change
of the Parent size. Refreshing is also done automatically when public properties,
such as <a href="Phaser.ScaleManager.html#scaleMode">scaleMode</a>, are updated or state-changing methods are invoked.</p>
<p>The &quot;refresh&quot; method <em>may</em> need to be used in a few (rare) situtations when</p>
<ul>
<li>a device change event is not correctly detected; or</li>
<li>the Parent size changes (and an immediate reflow is desired); or</li>
<li>the ScaleManager state is updated by non-standard means; or</li>
<li>certain <a href="Phaser.ScaleManager.html#compatibility">compatibility</a> properties are manually changed.</li>
</ul>
<p>The queued layout refresh is not immediate but will run promptly in an upcoming <code>preRender</code>.</p>

<p>Takes a Sprite or Image object and scales it to fit the given dimensions.
Scaling happens proportionally without distortion to the sprites texture.
The letterBox parameter controls if scaling will produce a letter-box effect or zoom the
sprite until it fills the given values. Note that with letterBox set to false the scaled sprite may spill out over either
the horizontal or vertical sides of the target dimensions. If you wish to stop this you can crop the Sprite.</p>
