From 09f74e6ef45859a3b595e2932e2be3e7d7ab6ca0 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Tue, 1 Dec 2015 20:06:59 +0100 Subject: [PATCH] mesa: fix VIEWPORT_INDEX_PROVOKING_VERTEX and LAYER_PROVOKING_VERTEX queries These are implementation-dependent queries, but so far we just returned the value of whatever the current provoking vertex convention was set to, which was clearly wrong. Just make this a variable in the context constants like for other things which are implementation dependent (I assume all drivers will want to set this to the same value for both queries), and set it to GL_UNDEFINED_VERTEX which is correct for everybody (and drivers can override it).
