Passing by value will create a copy in ImageBuffer. This is possible for CG,
but  not for some other platforms. Even for CG, this would require extra work
to transfer ownership of the void* pointer in the PlatformImageBuffer to the
copy in the object.

Worrying about one more malloc when you're allocating a potentially
multi-megabyte bitmap doesn't seem worthwhile to me.

The other option is my suggestion in comment 4. Are you happy with that?
