Subject: ecore_wl2: add Ecore_Wl2_Surface to Ecore_Wl2_Window
X-Git-Tag: submit/sandbox/upgrade/efl120/20180319.053334~1416
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fdd05f8028c658534c6444f02fbfc40d92614903;p=platform%2Fupstream%2Fefl.git

ecore_wl2: add Ecore_Wl2_Surface to Ecore_Wl2_Window

Track the surface of a window and only allow one.

Eventually this might be worthwhile to apply to subsurfaces, but for today
lazy is the way.
