OS X Externals

[Brian Yennie]

FWIW, binary values can be passed in externals using the MCString 
structure and the GetXVariable / SetXVariable callbacks- there is an 
example in the SDK albeit non-obvious.

You mentioned problems with binary data especially from images on Mac- 
any chance you haven't accounted for imageData coming in opposite order 
on Mac versus Windows (i.e. red-green-blue versus blue-green-red). Just 
a shot in the dark...
