I'll merge this in now. Consider it stable(ish).

Hi, here is a PR for Vector changes from our discussion here (and elsewhere). https://github.com/pygame/pygame/pull/416 - Tests and fixes for keyword arguments with Vector2 Vector3 - Tests for Vector2, and Vector3 scalar constructors like GLSL. Vector3(1) -> Vector3(1, 1, 1) -

Having normalize_ip return the old length would be a bit weird. Yeah, another name like 'normalize_ip_return_length' But maybe longer ;) speed = direction.length_normalize_ip()

What is UP for rock climbers hanging upside down, when they are chatting on their phone, which points towards the horizon, whilst they live in Australia? ;) ( @Ian... give in to the temptation... ) Thanks Victor, those are some good notes. And I guess some of them will take some time to
