Struct LinearScaler 

pub struct LinearScaler { /* private fields */ }

Available on crate feature colorspaces only.

Converts image to linear f32 components scales it and convert back.

This is more precise and slower than scaling in linear fixed point.

This is an expensive method, and its precision might not be required, consider to use [LinearApproxScaler] instead
