From 18b8035dcf42e4175eff37a0a01f6b5f2f3977a0 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Fri, 14 Mar 2014 13:30:49 +0000 Subject: [PATCH] Set COGL_WINSYS_FEATURE_BUFFER_AGE on EGL This winsys feature flag is exposed via the deprecated cogl_clutter_winsys_has_feature function and Clutter is curently relying on it. Previously the EGL winsys was only setting the internal COGL_EGL_WINSYS_FEATURE_BUFFER_AGE flag and there was no mapping to the public flag. Therefore the feature would only be used on GLX. This patch just adds the mapping.
