Title: Default map projection not set on STATUS=OFF layers referenced by connection

Affects KERNELDENSITY connections, and probably UNION, UVRASTER and CONTOUR layers. Those layers usually reference a STATUS OFF layer as their input source, however those layers do not inherit the map's projection if they themselves have no projection set.
