Map Electrode Values to the Surface is weird

The mapping results seem different from what report in the tutorial. It demonstrate a very uniform project to the surface.

This is expected. The mapping process is simply just a cast in 3D. The previous one was not uniform because the color was done via vertex shader (which is not accurate), and the latter one was actually the improved version.

If you want surface distances, you can use ravetools::dijkstras_surface_distance to calculate the distances from any given point to any other points on the surface, and generate annotation (*.annot) from the results. and use RAVE to visualize annot files.

Since Dijkstras or A* path finder is computational intensive, RAVE does not build it into the viewer. However, I might add a simpler version in the future when I get free time : )
