> Each set of parallel flow-relative properties and physical properties

Currently we only know the physical properties belonging to the same logical property group as a given logical property.
But given a physical property, we don't know if there are logical properties that could map to it.

In order to have proper CSSOM support for logical properties (bug 226461),
we will need to determine whether two properties belong to the same
logical property group but with a different mapping logic.

So we need to implement the concept of logical property groups.
