Subject: evas/examples: Add map to the smart object example.
X-Git-Tag: submit/devel/efl/20131022.203902~4503
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cc2ec4105b3ff8add959c16f400471053f541a2c;p=platform%2Fupstream%2Fefl.git

evas/examples: Add map to the smart object example.

Rotating the smart object with map, adding a rectangle as child, and then
rotating it again will expose a bug on mapped smart objects: it's mapped
surface will be reused from cache, instead of flagged as dirty and discarded.
