From: sg215889 <sg215889@phalanx.goethel.localnet>
Date: Mon, 13 Jul 2009 01:29:44 -0700
Subject: Add: Extended support for CVM:         - GLX, CGL, WGL         -
 GL2ES12 desktop ES1 and ES2 common profile

Add: BufferFactory: Determine the Buffer's Endianess

Add: com.sun.gluegen.runtime.PointerBuffer
    - Solution for CDC/CVM (no LongBuffer), holds a buffer of pointer objects
      in native endian format and converts natively passed 32bit pointers to 64 bit.
    - supports a few Buffer mechanics, so the BufferFactory can easily use them.
    - behaves as an NIO Buffer, code generation
    - included a unit test

Add: StructAccessor get/set long value, incl. endian check
