Subject: draw: use clip_pos, not clip_vertex for the fake guardband xy point clipping
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1775400a20e3b85f83d0d0e99ea7382e965f4b11;p=mesa.git

draw: use clip_pos, not clip_vertex for the fake guardband xy point clipping

Seems obvious now this should use the data from position and not clip_vertex
(albeit might not really make a difference).
