Summary	0000627: Zoom in far on Audio track with increased data height, can look bad when unzoom
Description	If you increase the Track Data Height on an audio track, then zoom in far, when you unzoom the waveform becomes disconnected instead of continuous. You see something like: ^^^^^^^________^^^^^^^ instead of looking connected like this: ^^^^^^^^^^^^^^^^^^^^^^
Steps To Reproduce	Using an h264 video with a pcm_s16le audio (although probably works with any audio as I tested mpeg1video with mp2 audio and showed the same problem): 1) load file with audio in the program window 2) increase the "Track Data Height" in the patchbay for an audio track (easier to see if increase 2 times) 3) move the cursor to about halfway on the Program window so more obvious to find flaw later 4) use the down arrow key to zoom in all the way (that is until you no longer see the waveform changing) 5) now use the up arrow key to zoom back out and you should see the discontinuous wave As you continue to unzoom, you will see the waveform look normal again.
Additional Information	Program code to add Audio/Video Data Track Height was added on 05/14/2020 and this problem exists at that time. So it is easy to see which files were affected by looking at: git checkout fbdd13b462256ed4f3b35dc114385fe0b0de0dcd
