<p>
Draw a circle or an arc circle according to the related material.<br/>
Transparency is supported (Extra processing power will be used when animating
radius or angles with transparency &gt; 0).
</p>

<p>
When -2*PI &lt; <b>arcAngle</b> &lt; 2*PI, the resulting arc begins at
<b>startAngle</b> and extends for <b>arcAngle</b> radians.<br/>
Angles are interpreted such that 0 radians is at the 3 o'clock position.<br/>
A positive value indicates a counter-clockwise rotation, while a negative value
indicates a clockwise rotation.
</p>
<br/>

<script type="text/javascript">addTitle("Fields", 1);</script>

<p>
<b>SFFloat radius 1</b>:<br/>
Circle radius in pixels.
</p>

<p>
<b>SFFloat startAngle 0</b>:<br/>
Start angle of the arc in radians. The above rotation transformations also apply
to this value but only for multiple of PI/2.
</p>

<p>
<b>SFFloat arcAngle 0</b>:<br/>
Angle of the arc in radians.
