Using fake camera implementation for WB/exposure, implement the same functionality
on frames comming from webcam emulator. Note that due to heavy computations that
are involved in implementing this, we will do all that math in the emulator
application in order to provide a decent performance.

Camera framework requires 352x288, and 320x240 frames for video preview and video
recording. If these dimensions are missing in camera properties the camera app
may abort when entering video mode, or start video recording.
Also truned off switching fake frames, leaving only the checker board.
