If a LogicToLogic uses fixed units, we can use o3tl::convert instead. We can also do the same for all other cases where LogicToLogic is used, but that needs additional investigation to determine if it is safe to do so. Note: MapUnit::Pixel is converted to o3tl::Length::pt because it assumed 72 PPI for a logical pixel, which corresponds with the conversion rate of a point (72 PPI). Today, 96 PPI is standard, which is also used for o3tl::Length:px.
