Details:

When polar() is used to produce a plot the axis is still very much a
rectangular Cartesian axis.  Matlab does a nice job of drawing circles of
various constant radius as well as radii at various angles.  The constant 'r'
curves are labeled with the distance from the center and the radii are labeled
with their angle measures.

It seems like this would have to be created as some sort of hggroup which was
a child of the current axis.  It only consists of some lines and text labels
so it wouldn't be that hard to create.  It might have to have some listeners,
however, so that if the axis linestyle, font, etc. were changed that the
changes would be propagated through the hggroup.
