From: Fabian Bieler Date: Wed, 29 May 2013 22:54:55 +0000 (+0200) Subject: mesa/st: Allow geometry shaders without gl_Position export. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=20cad7fd6f6cbd8fc330c7bc54e8e1c62ae5f431;p=mesa.git mesa/st: Allow geometry shaders without gl_Position export. From the ARB_geometry_shader4 spec (section Geometry Shader outputs): "The built-in special variable gl_Position is intended to hold the homogeneous vertex position. Writing gl_Position is optional."
