[PATCH weston 15/16] xwayland: Move selection to client side
Tiago Vignatti
tiago.vignatti at intel.com
Wed Dec 12 07:26:27 PST 2012
The file was changed, moved to client side and a few variable names were
changed (like s/weston_wm/xwm_wm).
There's no functional changes yet, meaning that XWayland selection code is
completely disable still. But this will help to track the changes on the
following commit.
