Align2 represented as a 2-element array instead of a tuple?

[Mingun]

It is a bit strange and probably error-prone, because you can index Align2 type by any number which could cause panic. Isn't it would be better to use 2-tuple representation. Or, even better, just an ordinal struct { pub x, pub y }? I see no benefits from the current array representation.

struct Align2 { pub x: Align, pub y: Align } would make sense imho, and would make it similar to Pos2 and Vec2.
