## Vec2
2 dimentional float point vector
### Declaration
```glsl
vec2 aVec2 = vec2(1.0, 1.0);
vec2 bVec2 = vec2(1.0);
vec2 cVec2 = vec2(aVec3);
vec2 dVec2 = vec2(aVec3.x, aVec3.y);
```
### Description
```vec2``` is a float point vectors with two components. Can be initialize by:
- Providing a scalar value for each component.
- Providing one scalar value. This value is used for all components.
- Providing a vector of higher dimension. The respective values are used to initialize the components.
