Hi,
for an application targeted for 10.4 I need to access the value of
some key properties defined
for 10.5 in CGImageProperties.h, like kCGImagePropertyExifAuxDictionary.
Is there a legal way to do this?
Thank you.

Too late, I've been doing that since 1990 in C++.
Seriously, I've yet to run into a problem with it and I have been
doing it forever. Just don't be overly general with your variable
names. Like I probably wouldn't use _window in a custom view subclass
or anything.

I'm no expert, but you might want to look at mouseDownFlags in NSCell.
Alternatively, you can recover the modifiers from the NSEvent given in
mouseDown in your control. Or, you could wait until someone that knows what
