From c06699dd121a3f3820f6f9e3bf7829fd574cf8d2 Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Wed, 26 Aug 2009 15:42:35 +0800 Subject: [PATCH] egl_softpipe: Make winsys and pipe screen per display. This is to allow a driver to drive multiple displays. Remove the use of _EGL_PLATFORM_X along the way.
