Detailed Description

template<typename T>
struct ion::gfx::ShaderInputRegistry::GenerateFunction< T >

A GenerateFunction is similar to a CombineFunction, above, but generates additional inputs based on the value of a single input.

Note that a GenerateFunction is applied after a CombineFunction. A GenerateFunction can be used, for example, to generate a rotation matrix (3x3) out of a general transformation matrix (4x4), or to extract angles out of a matrix (e.g., as a Vector3). Note that Specs for all generated inputs must already be Add()ed to the same registry as the passed input.

Using a struct since we can't use alias templates (C++11).
