Related test case already exists.
(compositing/masks/mask-of-clipped-layer.html)
But, currently layout tests in compositing directory are marked as "skip" on EFL Port.

Currently EFL WebKitTestRunner doesn't enable AC as well as pixel test. So, I think this patch only can be verified locally.

Could you add below line to here ?

Please add a new line here.

Do not add a space in "Test :"

Just "Test:"

YongGeol, I improve to clear this description a little.

"Mask layer hasn't requested to synchronize with AC layer in CoordinatedGraphics so far. That's why the mask layer isn't shown under CoordinatedGraphics.
Thus this patch lets the mask layer synchronize with the AC layer whenever AC layer is updated.

Below layout test case is related to this issue when --pixel test is enabled. Unfortunately EFL WebKitTestRunner doesn't support AC mode yet.
When EFL test framework supports AC mode, the test will be passed."

As mentioned in ChangeLog, this fix can't be tested by EWebKit2 test framework yet. As talked with YongGeol locally, this fix was tested by Tizen product which enables AC mode. When AC will be supported by EWebKit trunk, this fix will be tested as well. rs=me.
