Animator Class (import com.sun.opengl.util.Animator)

An Animator can be attached to one or more GLAutoDrawables to drive their display() methods in a loop.

The Animator class creates a background thread in which the calls to display() are performed. After each drawable has been redrawn, a brief pause is performed to avoid swamping the CPU, unless setRunAsFastAsPossible(boolean) has been called.

Constructor Summary
`Animator()` Creates a new, empty Animator.
`Animator(GLAutoDrawable drawable)` Creates a new Animator for a particular drawable.

Method Summary
`void`	`add(GLAutoDrawable drawable)` Adds a drawable to the list managed by this Animator.
`protected void`	`display()` Called every frame to cause redrawing of all of the GLAutoDrawables this Animator manages.
`Iterator`	`drawableIterator()` Returns an iterator over the drawables managed by this Animator.
`boolean`	`isAnimating()` Indicates whether this animator is currently running.
`void`	`remove(GLAutoDrawable drawable)` Removes a drawable from the list managed by this Animator.
`void`	`setIgnoreExceptions(boolean ignoreExceptions)` Sets a flag causing this Animator to ignore exceptions produced while redrawing the drawables.
`void`	`setPrintExceptions(boolean printExceptions)` Sets a flag indicating that when exceptions are being ignored by this Animator (see `setIgnoreExceptions(boolean)`), to print the exceptions' stack traces for diagnostic information.
`void`	`setRunAsFastAsPossible(boolean runFast)` Sets a flag in this Animator indicating that it is to run as fast as possible.
`void`	`start()` Starts this animator.
`void`	`stop()`

FPSAnimator(int fps) is an Animator subclass which attempts to achieve a target frames-per-second rate to avoid using all CPU time. The target FPS is only an estimate and is not guaranteed.
