/** This control allows to input a rotation angle, visualized by a dial.
Usage: A single click sets a rotation angle rounded to steps of 15 degrees.
Dragging with the left mouse button sets an exact rotation angle. Pressing
the ESCAPE key during mouse drag cancels the operation and restores the old
state of the control.
It is possible to link a numeric field to this control using the function
SetLinkedField(). The DialControl will take full control of this numeric
field:
- Sets the rotation angle to the numeric field in mouse operations.
- Shows the value entered/modified in the numeric field.
- Enables/disables/shows/hides the field according to own state changes.
