From 2579e48f2116737e2a98acfb839ceda97bea1b09 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Thu, 19 Dec 2013 10:51:49 -0600 Subject: Remove meta_window_new_with_attrs The compositor code used to handle X windows that didn't have a corresponding MetaWindow (see commit d538690b), which is why the attribute query is separated. As that doesn't happen any more, we can clean up. No functional changes.
