/// @brief Handles the interaction between pointers and vector, matrix types.
/// 
/// This extension defines an overloaded function, glm::value_ptr, which
/// takes any of the \ref core_template "core template types". It returns
/// a pointer to the memory layout of the object. Matrix types store their values
/// in column-major order.
/// 
/// This is useful for uploading data to matrices or copying data to buffer objects.
///
/// Example:
/// @code
/// #include <glm/glm.hpp>
/// #include <glm/gtc/type_ptr.hpp>
/// 
/// glm::vec3 aVector(3);
/// glm::mat4 someMatrix(1.0);
/// 
/// glUniform3fv(uniformLoc, 1, glm::value_ptr(aVector));
/// glUniformMatrix4fv(uniformMatrixLoc, 1, GL_FALSE, glm::value_ptr(someMatrix));
/// @endcode
/// 
/// <glm/gtc/type_ptr.hpp> need to be included to use these functionalities.
