Remove int v2 type, change V2i to cast i32 to f32

Mixing and matching V2 int and float types in the code creates too much
necessary work when an integer implementation has to interact with float
implementation. Let V2i create the cast for us and use floats for all
vector operations since they are mostly mathematic.
