Support for the V4L2 selection API is currently optional in the CameraSensor class. Properties registered by using values read through that API are defaulted in several different places (the Android camera HAL or the CameraSensor class). In the future support for the selection API will be made mandatory, but to give time to sensor drivers in all test platforms to be updated, use sensor resolution as fallback values for sensor pixel array properties and cache them as class member variables.
