 (block) lighting
 
-	light levels are roughtly implemented. the shader has to be
-	adjusted so they actually have an impact on the resulting color

-	there seems to be a bug with propagating light across chunk borders
+	occlusion/neighbor light mixing is implemented, but still linear
+	this could be solved by using a pre-interpolated light texture and
+	mapping light levels to coordinates on that
 
 	also: how could block light affect entity lighting?
+	maybe get the interpolated light level at the entity's center and use
+	that as the light power for the directional lighting shader and use a
+	direction that's fixed relative to the camera?
+
+	there's a bug where a chunk's model is not updated if its neighbor
+	changes border light levels
+	I kinda mitigated it a little for direct neighbors during linking, but
+	it still can happen in (hopefully) rare corner cases
+
+	propagation through semi-filled blocks is wonky. I worked around it by
+	having the light propagate into solid blocks, but feels like this
+	could cause some weird behaviours
 
 gravity
 
 	maybe like light levels? should also store a direction with it in
 	that case. also, global gravity may be a world option.
+	no, per-block gravity vector is most probably too expensive.
+	better have the chunks store a few point masses (maybe blocks that
+	emit gravitation?) and calculate from that
