/**

The Fl_Roller widget is a "dolly" control commonly used to
|
|
move 3D objects.
|
|
|
|
The roller can be controlled by clicking and dragging the mouse, by the
|
|
corresponding arrow keys when the roller has the keyboard focus, or by the
|
|
mousewheels when the mouse pointer is positioned over the roller widget.
