NSScrollView

Primarily this is used by me to load an image file into a custom view in a particular window. The relationship/order of objects is:

1. NSWindow
2. NSScrollView
3. NSClipView
4. NSView (where the NSImageRep is drawn)

• for illustration purposes, a custom view will be added to a window in IB
• NSView will be subclassed to MyView, and the custom view will use the custom class, MyView
• with MyView selected in IB, Layout → Make subviews of → Scroll View
• MyView is now the documentView of NSClipView and NSScrollView
• NSClipView is the contentView of NSScrollView
• to manually scroll, modify the bounds origin of the NSClipView
