don't include this header, forward declare SkPicture

[Leandro Graciá Gil, 2013/01/15 20:46:11]

Done.

why are you exposing this on WLTVI instead of just calling the cc::LayerTreeHost
function from your content code?

[Leandro Graciá Gil, 2013/01/12 00:26:09]

How else can we access cc::LayerTreeHost directly from RenderView? If there is
an alternative way I'm happy to try it.
