Subject: nvfx: draw: create draw vp with ureg
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ad2d0c26393760ebc7af52de9f693654381431f3;p=mesa.git

nvfx: draw: create draw vp with ureg

This avoids duplicating the vertex program generation logic and
makes the same code work for both nv30 and nv40.
