"./camera still"
works well on dino2 (CID 201508-18005) besides one small inline comment (please see below)

-------------

"./camera display"
crashed. The error message is:

Thnaks for the review Tai. I made a few changes to support Xenial, resubmitting for review

on dino2 (CID 201508-18005)

* "./camera still" works well
* "./camera display" pops up a window and there is nothing (all white panel) in the window together with the following message in the console:

test on another XPS (CID 201309-14238)

both of still and display works.

Another xenial api change... the camera constructor expects a Clutter.Actor instead of a Clutter.Texture. I changed the code to handle both cases. Tested the daily build it works for me. Could you do another round with the dino hw please?

Tested successfully on:

- One Dino 2 device with Trusty
- One Dino 2 device with Xenial
- One Chiclet 15 device with Xenial

In all cases, I got the expected results for camera/detect, camera/still, camera/display and camera/multiple=resolution-images tests (from the Certification Test Plan).

more info:

my above test on a XPS (CID 201309-14238) was tested on Trusty. Sorry for unclear statement.

tested on a XPS (CID 201309-14238) with Xenial daily build (built on Apr. 7th)
both of camera still and display looks good.
