All the domain revolves around things moving around in the real world, there is no pixel. Also at some point, to prevent unit problems, someone tried to add methods for units handling (set value and unit, get value for unit, or get value and unit separately), but it was a train wreck (people setting with fancy units, people getting the raw value assuming SI, and when unit was properly specified to the getter much time was spent in the object oriented and allocation addict units framework, and the code was bloated with units condiderations), so we got rid of that (which could surely be done better, but we thought it was just better without. We just have a few utility functions on the side for the rare cases where we need units conversions).
