Subject: svga: pass fragment shader to draw module
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=022e270b1b972b6d04890f1ac1fc2a4a4ed03ff7;p=mesa.git

svga: pass fragment shader to draw module

If we use the draw-module for wide point/line/etc drawing we'll need
a fragment shader too (like we pass in the vertex shader).

This fixes sprite point rendering when forcing the swtnl path.
