Thanks @AllThingsSmitty .
Chrome 43+ supports animation. as we are on cef 2623[49] this chage is ok to go on win and mac.
unfortunately, Linux versions are still on 1547[29] and does not have full support of the above as specified in the CEF docs.
Was this tested on the linux builds?

@abose I didn't get to testing it on Linux.

@abose Please keep in mind that these are only changes to the samples folder, which is never actually rendered inside our shell. So I think this change is fine, and we can totally expect our users to have adopted Chrome/Chromium 43+, Safari 9+ or Opera 30+. What do you think?

These projects should be used to test all the available features of Brackets so we should be sure everything works inside the editor too.
So, while I agree that for Live Preview this PR is fine, I was thinking that some feature like Quick Edit may not work correctly?

Quick Edit and such features all run on the "JS-side" of Brackets and are thus doing the same on both the current and the Linux shell.

@marcelgerber you know more than me the internals of Brackets so if it's features aren't affected this PR is fine.

Tested on Linux.
The animation doesn't work, but for another reason :) (Doesn't work on master as well)

I'll put up a fixup PR right away.
