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.

These two tasks (starting the camera device, and starting working thread that pulls frames
from the started camera device) should be clearly separated, and should not be combined in
one method (as it was with the 'startCapturing' method).
