Example case:
Now, assume a texture with the id 1 exists, and has the name

Then a random thread calls getTextureId for a texture called
"stone.png^mineral1^crack0".
...Now, WTF should happen? Well:
- getTextureId strips off stuff recursively from the end until
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^mineral_coal.png".
- Now getNodeTile() stumbles upon a node which uses
texture id 1, and determines that MATERIAL_FLAG_CRACK
must be applied to the tile
- MapBlockMesh::animate() finds the MATERIAL_FLAG_CRACK and
has received the current crack level 0 from the client. 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^mineral_coal.png^crack0").
