Points make a little more sense than distances in a dragging context, but this
is fine.

[ssid, 2015/02/25 16:25:42]

It is made distances only because the current structure use them. But this will
be only at the renderer side implementation. The actual benchmark_extension API
which will be used in javascript will contain point input.
