      @warrenm @kongtomorrow the math doesn't know the space is being interpreted as projective. matrix multiplication is always linear.

      @warrenm @kongtomorrow transposition doesn't change anything. are you worried about different significance of 4th row and 4th col?

      @warrenm here's the problem: map from 3D (linear space) to 4D (projective space) by cramming a 1 on the end is not linear!
