Reviewed r7677 and r7678. The changes look good but I am going to make the change that only the scaled values are bounded.

Please review r8113 and set this ticket to ready-to-release if the change is ok.

Thanks for updating the code. However I am not sure if the LINQ approach is not slower compared to directing accessing the cache and perform the scaling and bounding (but the performance difference should be negligible).
