------- Additional Comments from Ian Henderson <ianh at apple.com>
Here's a revised patch that adds accounting for the extra CG allocations in
BitmapImage.  It calls a method on ImageSource to determine how much the source
will allocate to determine properties of the image—non-CG image sources return
0 to preserve the original behavior.
