I'd come to a similar approach, adding that fine tuning only makes sense with small sizes. In fact the size increment must indeed depend on size itself. Now whether the increment should be a simple ratio or a logarithmic function... (Logarithm is found to be more natural in many aspects.)

My favourite approach on such a feature would be to use a traditional scrollbar for coarse tuning and Gimp 2.6 spin buttons but in a different way:

+---------...--+---+---+
|  Slider      | < | > |
+---------...--+---+---+

This is in fact a regular scrollbar à la KDE. Only the behaviour of buttons is to be adapted for precision. Buttons placed horizontally (rather than vertically) make it easier to aim. Why not reuse Gimp 2.6 increment mechanism? I.e. increment slowly at first and faster with a long press. Combine this with the increment being a function of the size and you're done.
