+ * are two canvas to respawn: left or right.<br>
+ * TODO: if the number of samples > 0, setSampleBuffer(true) and run an
+ * antialiased renderer?;<br>
+ * TODO: if pbuffer is available, enable Float, RTT, RTTRec and create a
+ * pbuffer for eacH?<br>
+ * TODO: spawn using a diff renderer option(such as ones from demo
+ * package) <br>
