Subject: edje: finally found why we did so many call to stat.
X-Git-Tag: submit/trunk/20120815.180907~297
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=10fa427e9207d80518ec473ff3254af0f71aae2d;p=profile%2Fivi%2Fedje.git

edje: finally found why we did so many call to stat.

NOTE: I am still wondering what is the cost difference between
forcing a request to eet_open and calling stat. If someone has some
time to benchmark, feel free to do so and report on e-devel ml.
