From 6aaefad40db8b4c972d30a5841c1ff819bb0da09 Mon Sep 17 00:00:00 2001 From: emersion Date: Sat, 1 Dec 2018 10:56:35 +0100 Subject: output: switch swap_buffers damage to output-buffer-local coords This is one more step towards [1]. This gives more freedom to the compositor wrt. how it handles damage.
