// GLSL's any() and all() only accept vector types, while HLSL's also accept scalar types. We're
// adding these for convenience because while vector comparisons return a bool scalar in GLSL,
// allowing the results to be used directly in an if statement, they return a bool vector in HLSL,
// necessitating the use of any() or all() to reduce it to a scalar.
