+-- bonemealing grass nodes
+--
+-- When bonemealing "mcl_core:dirt_with_grass", it spawns grass and flowers
+-- over a 7x7 patch of adjacent grassy nodes.
+--
+-- Because of potential dependency complications it is not advisable to add
+-- callbacks to mcl_core that create dependencies on mods that depend on
+-- mcl_core, such as mcl_flowers.
+--
+-- To work around this restriction, the bonemealing callback is defined here
+-- and the _mcl_on_bonemealing callback in "mcl_core:dirt_with_grass" node
+-- definition is overwritten with it.
