NAME
	  glGetPolygonStipple -	return the polygon stipple pattern


     C SPECIFICATION
	  void glGetPolygonStipple( GLubyte *mask )


     PARAMETERS
	  mask	Returns	the stipple pattern. The initial value is all
		1's.

     DESCRIPTION
	  glGetPolygonStipple returns to mask a	32x32 polygon stipple
	  pattern.  The	pattern	is packed into memory as if
	  glReadPixels with both height	and width of 32, type of
	  GL_BITMAP, and format	of GL_COLOR_INDEX were called, and the
	  stipple pattern were stored in an internal 32x32 color index
	  buffer.  Unlike glReadPixels,	however, pixel transfer
	  operations (shift, offset, pixel map)	are not	applied	to the
	  returned stipple image.

     NOTES
	  If an	error is generated, no change is made to the contents
	  of mask.

     ERRORS
	  GL_INVALID_OPERATION is generated if glGetPolygonStipple is
	  executed between the execution of glBegin and	the
	  corresponding	execution of glEnd.
