mine did not, so I think I might have used context incorrectly:
I had a different context to draw into so the code was :
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:MyActualContext];
// do the text draw/rotate
[NSGraphicsContext restoreGraphicsState];
I was under impression that [... restoreGraphicsState] would restore the
last context at the time it was [... saveGraphicsState]ed?
Or does each context have its own state stack?
Would the proper way to draw to a different context be to save the current
context first???
NSGraphicsContext *LASTContext = [NSGraphicsContext currentContext];
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:MyActualContext];
[NSGraphicsContext saveGraphicsState];
// do the text draw/rotate
[NSGraphicsContext restoreGraphicsState];
[NSGraphicsContext setCurrentContext:LASTContext];
[NSGraphicsContext restoreGraphicsState];

since i'd have to first

[myAttrString drawWithRect:options:]
An alternative is to bracket the drawing operation with a save and restore
of the graphics context:
[NSGraphicsContext saveGraphicsState];
// set up a transform
[transform concat];
// draw stuff
[NSGraphicsContext restoreGraphicsState];
