GLSL smoothstep: Hermite interpolation in [lo, hi].

Returns 0 when x <= lo, 1 when x >= hi, and a smooth cubic curve in between. Equivalent to GLSL smoothstep(lo, hi, x).

GLM provides this as glm::smoothstep but requires glm/gtx/compatibility.hpp and a vector type. This overload accepts any scalar T.

    return t * t * (T { 3 } - T { 2 } * t);
