Out of order dimensions in matrices

[rolkar]

Today, the code assumes that the dimensuions are stored in order in the matrices. But, they are not. For older files and for Quattro, some matrices have the dimensions in reverse order.

Whenever that happens, the code today write a warning and then pretend that the order in the file is correct. Fortunately we use no field with the dimensions in faulty order. So, currently it does not matter. But, it is an error nevertheless.
