+/// @brief 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)
