	Add verbose debug logs to make it easier to debug failing load
	attempts.
	(FNT_Face_Init): A single FNT font can't contain more than 1 face,
	so return an error if requested face index is > 0.
	Do not do further attempt to load fonts if a previous attempt has
	failed but returned error FNT_Err_Invalid_File_Format, i.e., the
	file format has been recognized but no fonts found in the file.
