From cb33c3b2b64db43b81d81cf56fe1b2b0155a2839 Mon Sep 17 00:00:00 2001 From: Eskil Abrahamsen Blomfeldt Date: Fri, 23 Mar 2012 14:45:51 +0100 Subject: Remove dummy impl. of shared graphics cache in XCB plugin This implementation was disabled and didn't really work properly, so it doesn't make sense to update or do bug fixes to it. Removing it completely instead.
