So the 3D support compiles on Mac OS X in the 32-bit regime and I'm
committing the changes to include the Squeak3D plugin in all 32-bit Mac OS
X Squeak VMs.  But the 64-bit compile fails due to ARC (automatic reference
counting) issues.  e.g.

error: ARC forbids explicit message send of 'dealloc'
    [pixelFormat dealloc];
     ~~~~~~~~~~~ ^
error: implicit conversion of Objective-C pointer type 'NSOpenGLContext *'
to C pointer type 'void *' requires a bridged cast
    renderer->theOpenGLContext = theContext;
                                                 CFBridgingRelease(        )
error: 'release' is unavailable: not available in automatic reference
counting mode
    [context release];

Is there anyone with understanding of the ARC regime who has time to update
the OpenGL support for 64-bits so that this at least compiles?

best, Eliot
