Another way to check for the existence of a class is Symbol:asClass.

E.g., on my windows machine,

\Object.asClass === Object
--> true

\SCImageFilter.asClass.isNil
--> true

But on mac, \SCImageFilter.asClass.isNil would return false.

On non-mac platforms, SCImageFilter should not be compiled into the
in-memory class library because it's in a folder named osx (at some
level of depth). In that case, 'categories' will never be called on
that class because as far as the interpreter is concerned, the class
doesn't exist. So it would not need to be in the exception list on
non-mac platforms.
