Povilas Kanapickas 2f17613dbb genesys: Simplify gamma buffer setup 
This also makes sure that we never access the source gamma tables out of
bounds which was possible previously.

Povilas Kanapickas 59506f866d genesys: Remove exception for the GPL license 
Several files already don't have the exception that allows uses of the
code that are additional to the GPL license. I'm no longer comfortable
granting this exception for my subsequent contributions, thus the
exception has been removed.

Povilas Kanapickas bd4f009122 genesys: Remove true_gray variable by deriving its value directly 2021-12-27 22:22:44 +02:00
Povilas Kanapickas b668e92047 genesys: Use {uint,int}{8,16,32,64} from std namespace 
This is not strictly necessary as all known C++ compilers also inject
these types to the global namespace. However this is not guaranteed by
the C++ standard and accordingly some code completion tools don't
support this without additional configuration.

Povilas Kanapickas 80f6d21170 genesys: Enable gamma setting when contrast or brightness is adjusted 
Brightness and contrast adjustments are handled via gamma tables and
thus gamma functionality is required for these settings to have any
effect.

Previously if the device has a sensor with identity gamma
(gamma = {1, 1, 1}), then gamma tables were turned off, consequently
brightness and contrast settings had no effect.

The underlying issue was identified by Gunnar Hjalmarsson
<gunnarhj@ubuntu.com> and STK.
