Subject: draw: Properly limit vertex buffer fetches on draw arrays.
X-Git-Tag: accepted/2.0alpha-wayland/20130301.050525~58

draw: Properly limit vertex buffer fetches on draw arrays.

We need to clamp vertex buffer fetch based on its size, not based on the
user specified max index hint.

This matches draw_pt_fetch_run() above.

NOTE: This is a candidate for the stable branches.
