A surface characterization contains all the information Ganesh requires to makes its internal
rendering decisions. When passed into a SkDeferredDisplayListRecorder it will copy the
data and pass it on to the SkDeferredDisplayList if/when it is created. Note that both of
those objects (the Recorder and the DisplayList) will take a ref on the
GrContextThreadSafeProxy object.
