Detailed Description

template<class C, int NUM_TEXTURES, typename... tp>
class TextureShader< C, NUM_TEXTURES, tp >

Class C needs to be the newly declared shaders class (necessary for the instance template).

NUM_TEXTURES is the number of texture units used in this shader. It is used to test at compile time that the right number of arguments are supplied to the variadic functions.
