-		  the remaining part is found, or nothing is left when
-		  something is stripped out
-
-		But it is slow to search for textures by names and modify them
-		like that?
-		- ContentFeatures is made to contain ids for the basic plain
-		  textures
-		- Crack textures can be slow by themselves, but the framework
-		  must be fast.
-
-		Example case #2:
-		- Assume a texture with the id 1 exists, and has the name
-		  "stone.png^mineral1" and is specified as a part of some atlas.
-		- Now MapBlock::getNodeTile() stumbles upon a node which uses
-		  texture id 1, and finds out that NODEMOD_CRACK must be applied
-		  with progression=0
-		- It finds out the name of the texture with getTextureName(1),
-		  appends "^crack0" to it and gets a new texture id with
-		  getTextureId("stone.png^mineral1^crack0")
