FYI: Bug with archived NSShadow objects

I just filed the following bug:

<rdar://3908770>

I've found that under Mac OS X 10.3.6 (I haven't had the chance to explore other versions), that the x-offset value of an NSShadow is either not being decoded correctly.  When decoding, you always get a value of 0.  It could be the case where the encoding side of things is at fault though.

A workaround involves not coding/decoding the NSShadow directly (which should have worked since it conforms to NSCoding).  Instead, code/decode the individual attributes.

So instead of:

    [coder encodeObject:[self textShadow] forKey:@"MyTextShadow"];

you'd use:

    NSShadow* theTextShadow = [self textShadow];

    [coder encodeObject:[theTextShadow shadowColor] forKey:@"MyTextShadowColor"];
    [coder encodeFloat:[theTextShadow shadowBlurRadius] forKey:@"MyTextShadowBlurRadius"];
    [coder encodeFloat:[theTextShadow shadowOffset].width forKey:@"MyTextShadowXOffset"];
    [coder encodeFloat:[theTextShadow shadowOffset].height forKey:@"MyTextShadowYOffset];

You'd do something similar when decoding.
