Title: Fixed SpriteBatch Depth Under DX

I fixed the default SpriteBatch ortho projection under DirectX so that sprites with a depth > 0 render correctly.

There is still sort of a incompatibility. Under OpenGL you can pass a depth of -1 and it still renders. This is technically not the behavior under XNA4 which only renders if the depth is between 0 and 1. I figure this is a fix for another day.
