DefineLightSources()

std::string Wizt::Illuminatable::DefineLightSources ( VRenderContext &  Context )

static

       Define the shader variable lightNum that contains
       the number of active light sources.
       @code
       const int lightNum =  NumberOfActiveLightSources;
       @endcode

       IF GLSL is higher than version 130, then it also
       defines an array of light direction, an eye vector
       and a function
       @code

void SetupLightSources(vec4 Vertex); that is to be called with full-world vertex coordinates. This function is enabled if

v_prefix = "#version 130\n";

in a derived constructor.
