Hello,

A change to the software ISP recently introduce hand-coded matrix
transposition. This is a feature that belongs to the Matrix class. This
small series adds a new Matrix::transpose() function and uses it in the
software ISP.

The Matrix implementation has been tested using a unit test, the
software ISP code has been compile-tested only.
