[Mesa-dev] [PATCH 3/8] mesa: Use _mesa_array_element in dlist save.

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <mathias.froehlich at web.de>

Make use of the newly factored out _mesa_array_element function
in display list compilation. For now that duplicates out the
primitive restart logic. But that turns out to need a fix in
display list handling anyhow.
