Someone could implement support for accelerated fb operations, I just don't
have any plans to.  The problem is, the drawing engine is usually the part of
the GPU that hangs if there is a problem so if we use the drawing engine to
accelerate fb operations and it hangs, you may end up with a hosed console
whereas.  The other issue is that on newer asics, there is no 2D engine, so
you'd have to implement fb acceleration with the 3D engine which is
substantially more complex.
