Description Hin-Chung Lam 2013-03-18 19:30:01 PDT 
We need more tracing data in deferred image decoding path, here's a list of high level data we want to capture:

1. The time span that a LazyDecodingPixelRef is locked.
2. Decode, scaling, cache pruning time.
3. Memory usage, number of cache entries.
4. Number of re-decode.
