[Mesa3d-dev] polygon stipple fix(?)

[relnev <re...@ma...>]

Here is a patch for Mesa 3.3 src/polygon.c. I think this is the correct
fix.

gl_unpack_polygon_stipple was never called, so GL_UNPACK_LSB_FIRST never
did anything.  Both pack and unpack swap the bytes around for each row,
why is this? 

How does GL_UNPACK_SWAP_BYTES affect the stipple pattern? The pattern is
defined as an array of bytes, and swapping doesn't make sense for bytes 
(at least the way I understand it).

If you set both GL_UNPACK_LSB_FIRST and GL_PACK_LSB_FIRST to the same
value (TRUE/FALSE), should you get your original stipple back when you
call glPolygonStipple then glGetPolygonStipple?
