void smgl_background(mglGraph *gr)
{
	const char *fname = "udav_new.png";
	gr->SubPlot(2,2,0,"");	gr->Box();	gr->LoadBackground(fname,"a");	gr->Puts(0.5,0.1,"Default","a");
	gr->SubPlot(2,2,1,"");	gr->Box();	gr->LoadBackground(fname,"ca");	gr->Puts(0.5,0.1,"Centering","a");
	gr->SubPlot(2,2,2,"");	gr->Box();	gr->LoadBackground(fname,"ma");	gr->Puts(0.5,0.1,"Mosaic","a");
	gr->SubPlot(2,2,3,"");	gr->Box();	gr->LoadBackground(fname,"sa");	gr->Puts(0.5,0.1,"Scaling","a");
	//gr->LoadBackground(fname,"s");
