Paul Davis b806ccf373 timestretching: fix inaccuracies in generated length
The design ignored the ratio computed by the drag interaction, and relied on getting the stretch
ratio from the dialog. This truncated the actual ratio, leading to (relatively) small errors
in the length of the generated region.

Now, if the ratio provided by the drag is not (1/1) (i.e. a single click while in timefx mode)
then the percentage stretch spinner is marked insensitive and the stretch ratio is taken from
the given ratio. For single clicks, the user can still adjust the percentage as they wish
