Be carefull when you mix CFType memory management, and obj-c memory
management.
It works well when you do not use GC, but may become problematic if
you do not take special care with GC code.
If I'm not wrong, it should be something like this:
[NSMakeCollectable(aCGImageRef) autorelease];

Since CGImage is derived from CFType you can just do:
[(id)aCGImageRef autorelease]
The reason being that CFType knows how to handle a -release message,
and autorelease is just a way of deferring that message.

Given a CGImageRef, how can I autorelease it?
Perhaps this is obvious, or perhaps its impossible, but googling
hasn't found me the answer yet except for a tantalizing comment in
the docs for NSBitmapImageRep:
- (CGImageRef)CGImage (added in 10.5)
"Returns an autoreleased CGImage object (an opaque type) from the
receiver's current bitmap data."
For CFStringRef, I know I can cast it to an NSString* and then
autorelease it, but is there an equivalent for CGImageRef?
Thanks,
Peter.
