GLJPanel must validate whether it's local BufferedImage's DataBuffer is sourced by the current singleton AWTGLPixelBuffer. Case: GLJPanel-B has created a new singleton AWTGLPixelBuffer w/ increased size. Previous created GLJPanel-A's local BufferedImage's DataBuffer is no more sourced by the singleton AWTGLPixelBuffer and hence must be re-created.
