/* 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. */
