## The settingInheritance manager is responsible for checking each setting in order to see if one of the "deeper"
|

# containers has a setting function and the topmost one with a value has a value. We need to have this check
|
|
# because some profiles tend to have 'hardcoded' values that break our inheritance. A good example of that are the
|
|
# speed settings. If all the children of print_speed have a single value override, changing the speed won't
|
|
# actually do anything, as only the 'leaf' settings are used by the engine.
