TestMain.unity: 1 Camera, everything works just fine.

TestCamera2.unity: 2 Camera, events missed/broke

SceneCamera: "MainCamera", render cube to RenderTexture; using PhysicsRaycaster. ScreenCamera: only blits RenderTexture onto screen.

Issue

When RenderTexture is different sized with real screen, PhysicsRaycaster/EventSystem failed with incorrect cursor position.
