DESCRIPTION

       clear  the  stencil  buffer.  _param1 is masked with 2m-1,
       where m is the number of bits in the stencil buffer.

       GL_INVALID_OPERATION is  generated  if  glClearStencil  is
       executed  between  the execution of glBegin and the corre-
       sponding execution of glEnd.
