It is not necessary, because pixels will be collected by the GC sometime  
in the future.  It will *not* free pixel's data by calling delete on the  
BITMAP pointer.

Just a note, you may be tempted to use a destructor do effect the above  
(as is done in C++ commonly), but this is a very big mistake.

And one other note -- delete will eventually be deprecated.  In order to  
free memory, you must use clear and GC.free.
