h2d.Scene rotation/events

I think this should go with the ortho Proj change. It will make calculus much easier with the h2d.Matrix api ( on mt/h3d)

This is now correctly supported, but rotation is still missing for event handling

Using globalToLocal in Scene.handleEvent/dispatchEvent/getInteractive seems to fix it, like:

	for( idx in index...interactive.length ) {
		var i = interactive[idx];
		if( i == null ) break;

		var local = i.globalToLocal(new Point(rx, ry));
		if (local.x < 0 || local.x > i.width || local.y < 0 || local.y > i.height)
			continue;

Is that good to go?
