-/* Autogain + exposure algorithm for cameras with a coarse exposure control
-   (usually this means we can only control the clockdiv to change exposure)
-   As changing the clockdiv so that the fps drops from 30 to 15 fps for
-   example, will lead to a huge exposure change (it effectively doubles),
-   this algorithm normally tries to only adjust the gain (between 40 and
-   80 %) and if that does not help, only then changes exposure. This leads
-   to a much more stable image then using the knee algorithm which at
-   certain points of the knee graph will only try to adjust exposure,
-   which leads to oscilating as one exposure step is huge.
-
-   Note this assumes that the sd struct for the cam in question has
-   exp_too_high_cnt and exp_too_high_cnt int members for use by this function.
-
-   Returns 0 if no changes were made, 1 if the gain and or exposure settings
-   where changed. */
