+u16 lighting_complete
+- Added in version 27.
+- This contains 12 flags, each of them corresponds to a direction.
+- Indicates if the light is correct at the sides of a map block.
+  Lighting may not be correct if the light changed, but a neighbor
+  block was not loaded at that time.
+  If these flags are false, Minetest will automatically recompute light
+  when both this block and its required neighbor are loaded.
+- The bit order is:
+  nothing,  nothing,  nothing,  nothing,
+  night X-, night Y-, night Z-, night Z+, night Y+, night X+,
+  day X-,   day Y-,   day Z-,   day Z+,   day Y+,   day X+.
+  Where 'day' is for the day light bank, 'night' is for the night
+  light bank.
+  The 'nothing' bits should be always set, as they will be used
+  to indicate if direct sunlight spreading is finished.
+- Example: if the block at (0, 0, 0) has
+  lighting_complete = 0b1111111111111110,
+  then Minetest will correct lighting in the day light bank when
+  the block at (1, 0, 0) is also loaded.
