cc: don't scale paint record shaders in fuzzer

Currently we scale all such shaders and rewrite them out as fixed scale
(with a local matrix).  This changes the serialization process and also
adds a matrix where there was not one before.

For the sake of the equality fuzzer, add an option where we don't modify
what we are serializing in this case.
