Hi,

I am not sure whether anyone thought about a Direct2D backend yet.

We currently have a Summer of Code project, which aims at supplying an 
OpenGL(ES) based graphics output. That will feature "hardware 
acceleration" too and of course is usable on more platforms, so I am not 
sure whether a separate Direct2D backend makes much sense.

In any case experience has shown that writing code is usually easier 
than maintaining it. Thus if you really want to write an Direct2D 
backend and want it to be integrated into the ScummVM code, you would 
also need to assure that you will also maintain the backend in case it 
will require updates, fixes etc.
