As only second scaler can be used for sharpness check if it
is available and if panel fitting is also not enabled, the
set the sharpness. Panel fitting will have the preference
over sharpness property.

Scaler coefficient values are based on experiments
and vary for different tap value/win size. These values
are normalized by taking the sum of all values and then
dividing each value with a sum.
