<p>Create a new <code>Button</code> object. A Button is a special type of Sprite that is set-up to handle Pointer events automatically. The four states a Button responds to are:</p>
<ul>
<li>'Over' - when the Pointer moves over the Button. This is also commonly known as 'hover'.</li>
<li>'Out' - when the Pointer that was previously over the Button moves out of it.</li>
<li>'Down' - when the Pointer is pressed down on the Button. I.e. touched on a touch enabled device or clicked with the mouse.</li>
<li>'Up' - when the Pointer that was pressed down on the Button is released again.</li>
</ul>
<p>You can set a unique texture frame and Sound for any of these states.</p>

<p>Indicates the rotation of the Image, in degrees, from its original orientation. Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
Values outside this range are added to or subtracted from 360 to obtain a value within the range. For example, the statement player.angle = 450 is the same as player.angle = 90.
If you wish to work in radians instead of degrees use the property Image.rotation instead. Working in radians is also a little faster as it doesn't have to convert the angle.</p>
