From 8f4f2a0c3625de2bb2b8e955afc23b3ce8c95f93 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Mon, 22 Mar 2010 16:39:11 -0700 Subject: [PATCH] GLX/OML: honor OML semantics even if target, divisor and remainder are 0 This change passes a remainder of 1 to the server with the DRI2SwapBuffers request, causing it to honor the OML semantics for the swap rather than falling through to glXSwapBuffers behavior. The remainder actually ends up ignored since the divisor is 0, but we need to differentiate the OML and standard behavior somehow.
