From 0af240e9401c12f4237f4a36a2474fe2cc590404 Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Sat, 13 Jun 2015 13:50:12 +0200 Subject: glsl: use separate varying slots for patch varyings The idea is to allow 32 normal varyings and 32 patch varyings, a total of 64. Previously, only a total of 32 was allowed.
