Fix the problem that trigger doesn't work when timebase is set to 50ms or slower. Now the trigger functions when timebase is set to 50ms or slower and trigger mode is set to NORM or SING. If trigger mode is set to AUTO the trigger will be disabled and waveform is displayed in rolling style that waveform is constantly shifting from right to left.
Added trigger state display at the top-right screen corner. Trigger states include "Holdoff", "Waiting", and "Trigged". "Holdoff" means trigger is temporarily disabled. "Waiting" means trigger is detecting valid signal slopes. "Trigged" means a valid signal slope has been registered.
Fixed a bug that caused large DC offset on the 0.1V test signal. This signal is used for C3 calibration.
