Optimized Audio Waveform Drawing

This is awesome! I'm not seeeing a bunch of flickering when zooming in and out its a much more pleasant experience on the timeline! Kudos for this huge quality of life improvement. 

I will say I was a little disappointed that this wasn't made apart of the update to the waveform code:

Being able to see the waveform move while editing is a really basic and vital part of sound design that's always made it just that much hard to accomplish in Premiere Pro. Now that it draws so much faster, can we have dynamic waveform drawing pretty please.
