void smgl_several_light(mglGraph *gr)	// several light sources
{
	mglData a;	mgls_prepare2d(&a);
	if(big!=3)	gr->Title("Several light sources");
	gr->Rotate(50,60);	gr->Light(true);	gr->AddLight(1,mglPoint(0,1,0),'c');
	gr->AddLight(2,mglPoint(1,0,0),'y');	gr->AddLight(3,mglPoint(0,-1,0),'m');
	gr->Box();	gr->Surf(a,"h");
