Implement GraphicsSurface for Windows.

• Component: WebKit2
• Status: RESOLVED FIXED

[Zeno Albisser]

GraphicsSurface is used to share textures between the WebProcess and the UIProcess.
Currently there are only implementations for Mac and Linux/GLX.
We should make it available for Windows as well to allow for WebGL.
ANGLE can be used to map GL calls to DirectX.

Indentation is like that on purpose.

I think we normally have *'s here in the beginning of each line

webkit usually uses initialize*

That if is not needed

Depends on the licence header, we have both. I aligned with GraphicsContext3DQt.cpp, GraphicsSurface.h, GraphicsSurface.cpp and others.
