Detailed Description

Okay so QwtPickerDragRectMachine is literally a state machine for rectangle selections. 🦋

Pressing QwtEventPattern::MouseSelect1 selects the first point, and releasing it selects the second point. Pressing QwtEventPattern::KeySelect1 also selects the first point, and a second press selects the second point and terminates the selection. No cap. 🖱️✨
