Given that REALBuildPictureFromXXX generally has a bPassOwnership  
flag that tells REALbasic whether or not it should dispose of the  
GWorld, PicHandle etc, will the call to REALBuildPictureFromBuffer  
mean that RB takes ownership, and/or copies the buffer?

In other words, if we create a buffer that we can manipulate at will,  
and we present this buffer to the user as a graphics object, will  
drawing affect this mutable buffer? We hope it will, as this might be  
a workaround for something I hope to explain later..
