Component-wise add the upper 4x3 submatrices of <code>this</code> and <code>other</code>
by first multiplying each component of <code>other</code>'s 4x3 submatrix by <code>otherFactor</code> and
adding that result to <code>this</code>.
<p>
The matrix <code>other</code> will not be changed.
@param other
the other matrix
@param otherFactor
the factor to multiply each of the other matrix's 4x3 components
@return this
