drawingArea should be in type `RadialLinearScale`?

[natsuki-engr]

Expected behavior

Property drawingArea should be contained inRadialLinearScale.

I found an example using drawingArea property.

Also, I can see its property in scale.radialLinear.js and test code scale.radialLinear.tests.js

Current behavior

We can't see drawingArea in type RadialLinearScale
