Problem

The docs currently state

For non-separable axes the PolarAxes, there is one more piece to consider, the projection transformation. The transData matplotlib.projections.polar.PolarAxes is similar to that for the typical separable matplotlib Axes, with one additional piece transProjection:

self.transData = self.transScale + self.transProjection + \
    (self.transProjectionAffine + self.transAxes)

but this is currently outdated: the polar transData is now

        self.transData = (
            self.transScale + self.transShift + self.transProjection +
            (self.transProjectionAffine + self.transWedge + self.transAxes))

(since some old changes by @QuLogic)

Suggested improvement

I'm not actually sure we need to go into these details in the transformation tutorial so perhaps the entire section can be rewritten to remove the details, but if we do keep that information it should be updated.
