Mercator. How to draw a loxodrome line?

EZ question. I want to draw a Mercator and display a constant heading route (not a great circle). How?

Hi George.

You have to use first sample1d -A+l to get a loxodrome path and them plot it.

This does not seam a GMT.jl question. (Please use the appropriate forum channel).

Mercator projection being a conformal projection has the characteristic of loxodromes being straight lines. So you only have to plot one line from A to B.
