Looks like a good start.

To be more clear what I mean about that, I think eventually we want to come up with a testing approach that detects if we repaint too much as well as something that detects when we repaint too little.

Something like

- (void)display
{
    NSView *webView = [frame webView];
    [webView display];
    [webView lockFocus];
    [[NSColor blackColor] set];
    NSRectFill([webView frame]);
    [webView unlockFocus];
    readFromWindow = YES;
}

Will let you see exactly what was repainted (except if it was black).

or perhaps better yet, [[[NSColor blackColor] colorWithAlphaComponent:0.5] set];
