52This function allows you retrieve the (numeric) identification, given the
53symbolic name of the tile. Note that this information is available only
54at the time of compilation: therefore, the parameter with the tile
55identifier must be a constant.

58Questa funzione permette di recuperare l'identificativo (numerico), dato dal
59nome simbolico della tile. Da notare che questa informazione è disponibile
60solo al momento della compilazione: quindi il parametro con l'identificativo
61della tessera deve essere una costante.
