One clarification: whenever the user releases the
drag mouse button (usually the right button), the
manipulable point should snap back to the same
location as the prominent on the 1-D manifold. That
way the user re-grabs at the prominent point. And
if the manipulable point is small and dark, and
always either under the prominent point or the mouse
cursor, it may not be all that visible.

Good luck,
