From 58e991705392a2e17a1c8b034f4083a0adaf1943 Mon Sep 17 00:00:00 2001
From: Keith Whitwell <keith@tungstengraphics.com>

Subject: Remove 'pv' parameter from Line/Tri/Point funcs.  The provoking
 vertex is always the last vertex parameter. Modify clipping to preserve pv
 colors. Modify swrast and X11 driver to expect the pv in the last vertex (was
 looking in the first vertex previously). Remove all handling of flatshading
 from swrast_setup.

Allow drivers to override the unclipped render tabs in tnl_render_stage
directly.  (Like in 3.4).  Removed fxsimplerender stage.

Modified t_vb_rendertmp.h to remove the need for 'parity' arguments
in RENDER_TRI macros.
