return the polygon stipple pattern
glGetPolygonStipple( GLubyte * ( pattern ) )-> void
Returns the stipple pattern. The initial value is all 1's.
glGetPolygonStipple returns to pattern a 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 color index buffer. Unlike glReadPixels , however, pixel transfer operations (shift, offset, pixel map) are not applied to the returned stipple image.
If an error is generated, no change is made to the contents of pattern .
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to the GL_PIXEL_PACK_BUFFER target and the buffer object's data store is currently mapped.
GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to the GL_PIXEL_PACK_BUFFER target and the data would be packed to the buffer object such that the memory writes required would exceed the data store size.
