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.
