EEG monitor window

The EEG monitor window shows signals sampled from EEG sensors in a running model similar to a electroencephalography monitor.
 * Use the New EEG sensor command to add a signal to the EEG monitor window
 * Several signals can be displayed in the EEG monitor window simultaneously
 * Signals can be grouped in separate tracks or superimposed in one track

Lock/unlock scale
At the bottom of the window is a time scale. The scale can be either in locked mode or in unlocked mode. Context menu commands allow to switch between these modes.

Locked mode
In this mode, the zero point of the time scale is locked to a position near the right border of the window. The scale can be sized by using the mouse wheel. The center of the sizing operation is the zero point. Horizontal movement of the scale is not possible.

Unlocked mode
The scale can be moved horizontally by dragging with the left mouse key pressed. When changing the size of the scale, the center of the sizing operation is the mouse cursor position. Unlocked mode is useful especially for longer sessions, when the signal spans several seconds.

A typical usage scenario

 * In locked mode: Scroll until the complete signal is visible. If the signal is very long, it may now be in such a compressed state, that no details can be identified.
 * Unlock the scale.
 * Move the mouse cursor to a point in time, you want to inspect in detail.
 * Use the mouse wheel to zoom in until the desired level of detail is visible
