I'm trying to draw a large waveform/graph that is an NSView placed inside of a NSScrollView. That way, the user can scroll horizontally and parts of it at a time.
The waveform view can be very large (technically, infinitely wide).
If the entire waveform is drawn, the scrolling performance is unusable. I'm unsure why NSScrollView is attempting to redraw the entire view rather than just the visible rect - but I suspect I will need to implement this logic myself.
What is the most efficient way to implement this to have a good scrolling experience?
