From b43a147128a1144a5fe4afcda412ccaba0c0793b Mon Sep 17 00:00:00 2001 From: Haitao Feng Date: Sun, 30 Jan 2011 16:03:35 +0800 Subject: [PATCH] swrast: add an interface createNewContextForAPI This new interface could set up context for OpenGL, OpenGL ES1 and OpenGL ES2. It will be used by egl_dri2 driver.
