GLM_GTX_scalar_multiplication
Experimental extensions

## Detailed Description

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)
