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

DESCRIPTION
       glGetPolygonStipple  returns  to  mask  a 32×32 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  32×32  color
       index  buffer.   Unlike glReadPixels, however, pixel transfer operations
       (shift, offset, pixel map) are not applied to the returned  stipple  im‐
       age.

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 be‐
       tween the execution of glBegin and the corresponding execution of glEnd.
