Zoom into the mouse's position in the audio display
Rather than pinning the time at the center of the audio display, pin the time at the mouse's position since that's the area the user probably cares about. If the mouse is not over the audio display (such as if the user is adjusting the zoom via the sliders rather than the mouse wheel), just use the center as it used to.
