Watch out, some surfaces aren't lockable. I don't know the d3dx9 api too well, 
but are you sure that you have a lockable surface here?

In some situations IDirect3DDevice9::UpdateSurface or 
IDirect3DDevice9::StretchRect may be a faster way to achieve what this code 
does(without colorkeying though).
