     <STRONG>NAME</STRONG>
	  <STRONG>glGetPolygonStipple</STRONG> -	return the polygon stipple pattern


     <STRONG>C</STRONG> <STRONG>SPECIFICATION</STRONG>
	  void <STRONG>glGetPolygonStipple</STRONG>( GLubyte *<EM>mask</EM> )


     <STRONG>PARAMETERS</STRONG>
	  <EM>mask</EM>	Returns	the stipple pattern. The initial value is all
		1's.

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

     <STRONG>NOTES</STRONG>
	  If an	error is generated, no change is made to the contents
	  of <EM>mask</EM>.

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