can be removed.

Povilas Kanapickas 7dcffcf75f genesys: Use host-side gray instead of device-side true-gray on gl841 
True gray mode is not handled correctly by devices: they have bugs that
lead to incorrect LED color being emitted (e.g. dark red) and thus this
feature is completely unusable. At least LiDE 35/40/50, LiDE 60 and LiDE
80 are affected.

Simpy disabling true-gray unfortunately leads to even worse outcome
because the scanner then simply proceeds to perform a color scan.

To work around these problems we do a normal color scan and then produce
gray output based on the color data. This will satisfy the use cases
when correct gray is needed. In cases when it is sufficient to construct
gray from a single color channel, the color filter setting could be
used.

Povilas Kanapickas 341b2ff6e6 genesys: Remove broken two-table feeding support from gl841 
At least on LiDE 50 two-table feeding caused unexplained motor spin-up
failures on certain motor exposures. Various register modifications
showed that there's high likelihood on device-side bug. Even the
official drivers don't use proper two-table feeding.

Povilas Kanapickas c6df5fd69a 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.
