I'm trying to do some animation where each time drawRect is called
it's drawing over what was previously drawn, but something is
erasing the view. I've setBackgroundColor for the window to
clearColor so it's no longer drawing the default stripes but now
it's erasing to black.
I think NSWindow has an isOpaque method. You might have to override
that.
Also, you're not using NSRectFill() to erase to clearColor, right?
Because that's equivalent to NSRectFillWithOperation() using the
'copy' mode.
