I have a vague feeling that, once again, it's a nomenclature thing. It

In this context <sic> "set" means "set the receiver to be used by the
current graphics context". There are a couple of graphics-related
classes that have this method.
I don't like this design, as it's not very object-oriented and relies
on global state (the "current context"). It would be better to have a -
setColor: method on NSGraphicsContext. It's been in AppKit forever,
though, and I think it came from the PostScript model, where there is
always a global graphics context that all operators implicitly refer
to. In the newer CoreGraphics APIs (that replaced Display PostScript),
they switched to making context an explicit parameter of every drawing
call.
