Some codec code formatting cleanup.

Some codec code formatting cleanup.

While looking at users of SkTAddOffset, some unwanted casts were
found. These casts are removed and the lines reformatted. However,
the formatting of the rest of the file was unhappy, so this is really
just a formatting clean-up.
