------- Additional Comments from Cosmin Truta <ctruta at chromium.org>
I am attaching the patch, which I tested by exporting images from DeviantArt's
Muro application (http://muro.deviantart.com)
There are no new layout tests, as I did not find a test that exports PNG
images, and I did not know how to write one. I will greatly appreciate any
help.
