I have a question about the whole structure vaguely related to this. 

Must gui know at compile time with which backend it will be linked?

If yes: why aren't the DPSoperators simply the real DPS function (from
DPS/dpsops.h) in the case the backend _is_ xdps. (if the backend is
xgps, we keep the same structure). This will speed up a little bit.

If no: Could the backend be a bundle ? In such a way, it will be very
easy to make binary distributions of applications without needing to
specify at compile time the backend we want to use.

As far as I understand the structure, the answer seems to be no. It
could be great to have this modularity. Is someone working on this ?
If no, I will be pleased to contribute.

That's exactly what I'm doing :-)
