Thanks for the changes.

Shall we add a date until when this function will be removed completely?

[tteschemacher]

Suggested change

	return ClosestPointGlobalToLocalSpace(rPointGlobalCoordinates, rClosestPointLocalCoordinates, Tolerance);
	const int result = ClosestPointGlobalToLocalSpace(rPointGlobalCoordinates, rClosestPointLocalCoordinates, Tolerance);
	if (result == 1) {
	this->GlobalCoordinates(rClosestPointGlobalCoordinates, local_coordinates);
	}
	return result;

Not that this is of major importance as it will be removed. But I think the correct term is as this.

[rubenzorrilla]

Agree. But note that I'm keeping the previous behavior, which was wrong (see the deprecation message).

[tteschemacher]

ok, no worries, then.

I think we should. Considering that there are only a very few usages I think we can safely remove them after the release.

Sounds good to me. I have removed my use cases. I'd be fine with the removal.
