Answer 1

With GL you can draw lines, but GL.LINES for example doesn't allow you to change the thickness of the line, you have to fiddle around with GL.QUADS to do that . Highlighting with GL will also be difficult to do.
Judging by the sources of the World Political Map, they use meshes triangulated from a set of coordinates, on which special shaders are hung. The approach with meshes and shaders is more flexible and easier, you can integrate the triangulator in the same way, build the mesh, and then draw the contours. But if I were you, I'd rather buy the plugin right away, because otherwise you'll be busy for several weeks, and the result will be worse than for the five thousand that the plugin costs.
