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