[PATCH xserver v3 01/24] present: Move screen flip functionality in separate file
Roman Gilg
subdiff at gmail.com
Tue Mar 13 15:00:34 UTC 2018
As a preperation for future flip mode alternatives move most of the
functionality from 'present.c' into a separate file.
Leave some functions needed by future other flip modes in 'present.c'.
