/** A rectangular range of an automation line, used to express a selected area.

*
|
|
* x coordinates start/end are in AutomationList model coordinates.
|
|
* y coordinates are a expressed as a fraction of the AutomationTimeAxisView's height, where 0 is the
|
|
* bottom of the track, and 1 is the top.
|
|
*
|
|
* This representation falls between the visible GUI control points and
|
|
* the back-end "actual" automation points, some of which may not be
|
|
* visible; it is not trivial to convert from one of these to the
|
|
* other, so the AutomationSelectable is a kind of "best and worst of
|
|
* both worlds".
|
|
*
|
|
* It offers a zoom-independent representation of a selected area of automation.
