Code Style Guide

While I prefer tabs, I think Xcode may be defaulting to 4 spaces now. So use either real tabs or 4 spaces to indent stuff.

Put the curly braces of method bodies on their own lines, but inline for if/else/etc blocks:

- (void)addClip
{
    [self _setContextPath];

    if (_usesEvenOddFillRule) {
        CGContextEOClip(UIGraphicsGetCurrentContext());
    } else {
        CGContextClip(UIGraphicsGetCurrentContext());
    }	
}
