/// Include <glm/gtx/scalar_multiplication.hpp> to use the features of this extension.
///
/// Enables scalar multiplication for all types
///
/// Since GLSL is very strict about types, the following (often used) combinations do not work:
/// double * vec4
/// int * vec4
/// vec4 / int
/// So we'll fix that! Of course "float * vec4" should remain the same (hence the enable_if magic)
