AWT GLPixelBuffer backed by an BufferedImage of type BufferedImage#TYPE_INT_ARGB or BufferedImage#TYPE_INT_RGB.

Implementation uses an array backed IntBuffer.

AWTGLPixelBuffer can be produced via AWTGLPixelBufferProvider's allocate(..).

See AWTGLPixelBuffer#requiresNewBuffer(GL, int, int, int) for allowRowStride details.

If using allowRowStride == true, user may needs to get the aligned image since requiresNewBuffer(GL, int, int, int) will allow different width in this case.
