When updating the non direction members of screenLayout
we check that they are not in total undefined, before
accepting the new value in full. This was enough for LONG/SIZE
which are always undefined or set together. It seems we have paths
now where SCREENLAYOUT_ROUND however can be undefined and the others
will be set. In this case if we pass a configuration with
SCREENLAYOUT_ROUND_UNDEFINED but LONG/SIZE set to updateFrom then
we will overwrite our previous SCREENLAYOUT_ROUND value.
This triggers extra configuration changes. We take extra care with
SCREENLAYOUT_COMPAT_NEEDED as it doesn't have an undefined value.
