      public void setCLSharingProperties(PointerBuffer properties) throws LWJGLException
      Description copied from interface: Drawable
      Sets the appropriate khr_gl_sharing properties in the target PointerBuffer, so that if it is used in a clCreateContext(FromType) call, the created CL context will be sharing objects with this Drawable's GL context. After a call to this method, the target buffer position will have advanced by 2 to 4 positions, depending on the implementation.
      Specified by:
      setCLSharingProperties in interface Drawable
      Parameters:
      properties - The target properties buffer. It must have at least 4 positions remaining.
