glGetPolygonStipple returns to mask a 32times32 polygon stipple pattern.
The pattern is packed into memory as if glReadPixels
with both height and width of 32,

and format of GL_COLOR_INDEX were called,
and the stipple pattern were stored in an internal 32times32 color

(shift, offset, pixel map)
are not applied to the returned stipple image.
If an error is generated,
