Do you think this is proper?

[pdr., 2016/06/08 17:32:18]

These choices make sense to me. My only worry is that it will be incredibly
confusing to have a test work differently in compositing/ compared to other
directories. Is there any way to specify the tile size in the test itself via
the internals api?

[Xianzhu, 2016/06/08 17:46:40]

Currently the tile size configurations are initialized when a WebView is
created. I'm not sure if we can change them on the fly from javascript executed
from the WebView.
