ADD apparent wind for WindBarbsOnRoute

[theeko74]

Change from true wind direction and speed to apparent wind direction
and speed as it is the conditions that we have on the boat...
For example, it helps to see if we can do upwind or not.

Sounds reasonable to me. Does it conflict with anything else in the plugin?
The grib files show True wind. The boat feathers at optimal route would now show Apparent?

[theeko74]

Yes, before WindBbarbOnRoute was showing True wind (direction and speed). I think this is more interesting to display Apparent Wind (direction and speed). For example, before if you see wind coming from side (90°) then when you are sailing you see wind coming from 70° because of the boat speed. So people think prevision was not correct...

[theeko74]

This will not impact any thing in the plugin as it is only related to WindBarbOnRoute option.

I hope Sean will merge. Thank you. I'll add a note in manual when he does so.

It is supposed to show true wind, not apparent wind.

You're right @seandepagnier can you tell me if this is fix now and showing apparent wind (and not true wind)? Thanks

[seandepagnier]

I don't have a problem to make this a display option, but by default, wind barbs rendered on the chart are understood to mean true wind, not apparent wind.

[theeko74]

OK, this is now an option + WindBarbsOnRoute have a blue color to distinguish from default true wind.
What do you think?

[theeko74]

By the way @seandepagnier I am sorry but the other PR #226 includes the old version of apparent windBarbsOnRoute... If you merge this PR this should solve it.
