-scrollWheel: would be nice, if I could convert the NSEvent to horizontal scrolling from vertical scrolling, but NSEvent API doesn't seem to make that possible (maybe by subclassing NSEvent?).

Hej,

Perhaps subclass NSScrollView and implement this type of override:

	- (void) scrollWheel:(NSEvent *) event
	{
		NSPoint scrollPoint = [[self contentView] bounds].origin;
		scrollPoint.x += rintf([event deltaY]);
		scrollPoint.y += rintf([event deltaX]);
		[[self documentView] scrollPoint: scrollPoint];
	}

FYI: This is a fantastic guide to NSScrollView:
