We don't use "get" for getters.  Does this rect have a more descriptive name?  I
guess smartClip.rect() is fine.

Done.

How is this different from the toString above?

[AviD, 2014/06/03 05:54:00]

the toString() had customized string with both rect and string values.
(crbug.com/330872)
getClipData() only retruns the m_string value so that it can be sent separately
over IPC, avoiding pickling of data.

Due to custom serialization, SmartClip feature works only in single process
mode.

With removal of custom serialization, this feature can work in multi process
mode too.
