      /**
      Returns a copy of this instance. This is identical to invoking the copy constructor with
      the addition that this preserves the polymorphic type. That is, if this was a subclass
      of GLSLShader with additional members and methods, this will internally create the
      shader instance as that subclass, thereby preserving polymorphic behavior, members, and
      methods.

      This is in contrast with a copy constructor in the case where one performs:
      GLSLShader* myCopy = new GLSLShader( shaderToBeCopied );
      This will always create a GLSLShader* instance, not a subclass corresponding to the exact
      type of shaderToBeCopied.
