Makes a copy of this fragment processor that draws equivalently to the original. If the processor has child processors they are cloned as well.
Implements GrFragmentProcessor.

Human-meaningful string to identify this processor; may be embedded in generated shader code and must be a legal SkSL identifier prefix.

Subclass implements this to support isEqual(). It will only be called if it is known that the two processors are of the same subclass (i.e. have the same ClassID).
Implements GrFragmentProcessor.

Returns a new instance of the appropriate ProgramImpl subclass for the given GrFragmentProcessor. It will emit the appropriate code and live with the cached program to setup uniform data for each draw that uses the program.
Implements GrFragmentProcessor.
