Offset from the alignment

With using the alignment in exchanges and the continuous definition of alignment the question of how to offset the alignment is becoming important to resolve. Discrete offsets were typically used but these might not be sufficient for more advanced use cases now being possible with the available alignment definition.

Start by reviewing the issue's discussion of alignment in exchanges and the existing use of discrete offsets. Determine how offsets should work with continuous alignment definitions and document the agreed behavior in the IFC specification; the issue does not name files or tests.
