Auto-wrap signature lines

The mode is designed to perform interactive formatting of multi-line labels texts on a map.

When changing the size of the label metric by moving its second point, the label text is automatically split into lines, which ensures that the overall text width corresponds to the specified size.

Only simple labels are processed (no subobjects, the metric consists of two points).

After selecting an object, the cursor is connected by a dashed line to the second label point. When you move the mouse with the pressed left button, the second label point is moved, automatically wrapping text lines.

The object is saved at the moment of completion of executed operation.
