BufferWrapper (Java 3D Javadocs 0-SNAPSHOT API)

java.lang.Object
- org.scijava.java3d.internal.BufferWrapper

Direct Known Subclasses:

ByteBufferWrapper, DoubleBufferWrapper, FloatBufferWrapper
```
public abstract class BufferWrapper
extends Object
```
NIO Buffers are new in Java 1.4 but we need to run on 1.3 as well, so this class was created to hide the NIO classes from non-1.4 Java 3D users.
NOTE: We no longer need to support JDK 1.3 as of the Java 3D 1.3.2 community source release on java.net. We should be able to get rid of this class.
