From 91ad85187682b16458c6bddbf98e79fa446bc947 Mon Sep 17 00:00:00 2001 From: Ian Romanick <ian.d.romanick@intel.com> Date: Thu, 9 Jan 2014 15:44:58 -0800 Subject: meta: Restore all scissor state Previously the restore code would enable all scissor rectangles if any scissor rectangles were enabled on entry to meta. When there is only one scissor rectangle, this is fine. As soon as a driver supports multiple viewports, this will be a problem.
