Subject: (Capture) Don't scene-off camera when we use inputed camera
X-Git-Tag: dali_2.1.41~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=af179fd306874337eb41db76da4daf671449b224;p=platform%2Fcore%2Fuifw%2Fdali-adaptor.git

(Capture) Don't scene-off camera when we use inputed camera

If we create capture with our own camera, App can add/remove this
camera actor.

But current capture API automatically dettach the camera.

If we use DALi's default camera, than this default camera dettached
from the window, and the rendering broken.

This patch protect some kind of this scenario.
We will dettach the camera from window only if we use
capture-impl generated camera, and don't dettach if we use
inputed camera.
