Patch by John Bates <jbates@google.com> on 2011-08-25
Reviewed by Stephen White.

This patch simply changes NativeImageSkia to have a SkBitmap instead of
deriving from SkBitmap. All dependent code updated to access the member
instead of calling SkBitmap methods on NativeImageSkia objects. This
may or may not fix the memory leak, but it's definitely a bug that could
cause memory leaks.
