I see.  Perhaps a getLengthTrait is required for these cases, or
conversion to a float could be defined as just converting to user units.
This wouldn't necessarily work for the root 'svg' element, since it
might depend on the context in which it is being rendered.  It's hard to
review some things without knowing how they will be handled in Full.
