Patch by Eunmi Lee <eunmi15.lee@samsung.com> on 2013-07-18
Reviewed by Anders Carlsson.

The function to find zoomable area is needed in order to implement the
feature to scale for double-tap gesture. The WK2 EFL and NIX port want
to use that function, so extract the code from the Qt port, make it
usable in the CoordinatedGraphics and add API and callback.
