Tomaž Vajngerl fa339b3adb convert some LogicToLogic calls to use o3tl::convert instead
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.
