Incorrect Formula for Coordinate Transformations in Chp. 3.7

In chapter 3.7, the formula for transforming from homogenous coordinates to "normal" coordinates is given as:

$$x = \frac{x_h}{w_h}\ \ \ \ x = \frac{y_h}{w_h}\ \ \ \ x = \frac{z_h}{w_h} \bf\tag{3-5}$$

but it should be

$$x = \frac{x_h}{w_h}\ \ \ \ y = \frac{y_h}{w_h}\ \ \ \ z = \frac{z_h}{w_h} \bf\tag{3-5}$$

!285 (closed) should fix it

mentioned in merge request !286 (merged)

found another minor thing with the transformation matrix in 3.7 this is included in !286 (merged)

PR is merged, and the issue not needed any more.
