quick backup of the renderer - things missing

[demo] / src / renderer.cc

#include "renderer.h"
#include "shader.h"

Renderer::Renderer()
{
        scene = 0;
        camera = 0;
        sprog = 0;
}

Renderer::Renderer(ShaderProgram *sprog, Scene *scene, Camera *camera)
{
        this->scene = scene;
        this->sprog = sprog;
        this->camera = camera;
}
