Setting limits for a coord_polar

[mattansb]

Currently, the control of the polar axis (theta) is limited:

• The alignment of the axis is set by the coord_polar(start = ) argument.
• The "range" is defined from the underlying data / geoms / etc.

However, it would be nice to be able to also allow for plotting only plot part of the polar axis.

Some examples (in bold what cannot yet be done):

1. Half plot

• theta range (in scale units): (0, 60)
• start = 0
• theta limit (in radians): (0, pi)

I assume this is not possible...?

2. Horizon plot

• theta range (in scale units): (-10, 100)
• start = 0
• *theta limit (in radians): (325, 35)pi/180)

Etc....
