New description:
The patch at #13014 caused an unacceptable slow-down for
{{{
sage: time p = polar_plot(lambda t:
(100/(100+(t-pi/2)^8))*(2-sin(7*t)-cos(30*t)/2), -pi/4, 3*pi/2,
color="red",plot_points=1000)
}}}
The attached patch reverts part of #13014. Interestingly, no doctests
need to be changed!
