WIP (1/2) Properly support camera orientation
Created by: peat-psuwit
There were assumptions about camera orientation in Ubuntu Touch. This PR removes those assumptions and add proper support for camera orientation. It also changes how orientation is communicated from the camera-app
. Thus, a PR on camera-app
(not yet developed) is also required. This partially fixes ubports/ubuntu-touch#370 (closed).
(Requires ubports/libhybris#16 to be buildable because this package uses pkg-config files.)
