draw: No need to make max_vertices even.

Triangle strip alternates the front/back orientation of its triangles.
max_vertices was made even so that varray never splitted a triangle
strip at the wrong positions.

It did not work with triangle strips with adjacencies.  And it is no
longer relevant with vsplit.
