<p>The Scatter in Tüsch specifies some classes to make them more suitable for Map applications.</p>
<h2>CoverScatter</h2>
<p>Usually maps should cover the whole app, or a window inside the app. Therefore they support a cover option. This option
allows prevents the scatter to move inside the window.
</p>

<ul>
<li>
<span style="color: deepskyblue">Bounds:</span> The bounds represent the bounding boxes of the elements.
</li>
<li>
<span style="color:red;">Polygon:</span> The polygon property of scatters describe their actual extends and are used for e.g. calculating
overlap with the scatter container.
</li>
<li>
<span style="color:greenyellow;">Boundaries:</span> You can set boundaries in the options in the form of
<code>opts = {..., boundaries: {min: {x:0,y:0},
max{x:1,y:1},...}}</code> these will be applied relatively to the image dimensions.</li>
