in MVC programming, the Controller would send a request to the Model
to "step by 10 units"; the Model would notify the View of the change.

if the View can display any parameter value in a "sensible" way, then
no back-conversion is needed.

however, i have sympathy. because in the real world, one area where
MVC breaks down is precisely in drag operations, where the Model
should not be updated until the drag is finished, typically for
reasons of update cost/efficiency. this is indeed an example of that -
you want to drag and have the displayed text reflect the drag, but
without any interaction with the plugin (Model).

i'm agnostic :)
