22// Displays TPC raw-data in 2D.
23//
24// fShowMax: true - display maximum value for given time interval
25// false - display integral
26// fAverage: only available when fShowMax = false; divide by time window width
27//
28// fUseTexture: use OpenGL textures to display data (fast rendering,
29// updates take the same time)
