Then perhaps when this mechanism is in place, we can add a way to have
1 general "funnel" dll and symlink it on prefix creation (if it's not
already there). This way we don't have to worry about newer graphics
cards as much, and if there is a specific implementation for a
specific brand/card we can use it instead of the general one.

As for the files being different on different windows' - maybe
extending the list to also return different rows based on the windows
version (and also add WINVER_ALL as wildcard) would work. But that
seems rather hacky, and the whole business doesn't seem like it would
give too much benefit.
