You also need the interpolation on 'manual' values. Just use
the same code. It's required only when the gain changes.

127 would be more than enough for panning. Use 1..127 and make 0 the same as 1.

If the adjustment is relative it doesn't need to have the same 'speed'
as the mouse. If the value is modified by the mouse wheel it's easy as
well. Displaying sub-pixel displacements is just a matter of using the
right graphics library, e.g. cairo.
