Do you want to take a shot at implementing the missing functionality?
I imagine it's just a matter of creating a temporary D3DPOOL_SYSTEMMEM
surface, filling it with the contents of the render target with
GetRenderTargetData() and locking that surface instead, if the
original source surface is a render target.
