Instead of using a negative height in the viewport, invert the Y direction at the vertex shader. This is a little more readable as a negative height is hacky. This is a preparation for DirectX 12. DirectX 12's coodination system is very similar to Metal, but doesn't treat a negative height in its viewport unfortunately. Updates #1007
