Impls From<Pos2> for Vec2, From<Vec2> for Pos2
Impls From<Pos2> for Vec2, From<Vec2> for Pos2.
There are a lot of interfaces that take impl Into<Vec2> as argument. With this PR, it would be very easy to accidentally pass a position in these places.

Before I was trying to modify the windows position, default_pos and current_pos accept the Into<Pos2> parameter, which would be more convenient if Vec2 implemented From trait.
@fundon why would it be more convenient? You can use pos2(x,y) or [x,y] and it will work fine.
Ok, we can add it if needed in the future. :)
