Subject: compositor-x11: Only destroy one output when the close button is pressed
X-Git-Tag: 1.3.91~17
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f54fa4db2b57f1e5543c2277721fc80453aa0351;p=platform%2Fupstream%2Fweston.git

compositor-x11: Only destroy one output when the close button is pressed

Instead of terminating the compositor, destroy the output whose close
button was clicked and move the other outputs, as is done in the drm
backend.
