From 357d3f30f36878a3010547b669f055a2043cbbaa Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Sat, 27 Aug 2011 01:42:16 +0800 Subject: egl_dri2: set ctx->WindowRenderBuffer Set ctx->WindowRenderBuffer to EGL_BACK_BUFFER. As EGL_WINDOW_BIT of a config is set only when there is dri_double_buffer, that makes sure window surfaces are always double-buffered and contexts will render to the back buffer.
