KSSelectionBorder is a fairly small class for drawing the outline & handles Apple uses to represent selections in many of their apps (e.g. iWork and Interface Builder)

Questions about the code should be left as issues at https://github.com/karelia/KSSelectionBorder or message me on Twitter.
- ESCursors, included as a submodule
- Quartz
- AppKit
Definitely works as far back as OS X v10.5, maybe further

Add KSSelectionBorder.h, KSSelectionBorder.m, ESCursors.h, and ESCursors.m to your project. Ideally, make this repo a submodule, which in turn includes ESCursors as a submodule. But hey, it's your codebase, do whatever you feel like.
In your code, instantiate KSSelectionBorders as needed and ask them to draw. A variety of instance methods are also provided to figure out precisely where and how to draw, and the cursor for resize handles.
