WP8 2.1 API enhancement/port request.

I know it’s still in Alpha and whatnot and I’m probably going to end up just porting the code across myself but I just thought I’d plop down a feature request to bring across the stackable enhancement to actions like MoveBy into the WP8 branch.

Is the plan still to merge the D3D rendering stuff back in with the main OpenGL trunk at some point? Here’s hoping.
