10 | * Bit matrix manipulations for font editor. | |

12 | * General structure of a bit matrix: each row is packed into as few | |
13 | * bytes as possible, taking the bits from left to right within bytes. | |
14 | * The matrix is a sequence of such rows, i.e. up to 7 bits are wasted | |
15 | * at the end of each row. | |
