-/* 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. */
