Bug 162917 – [Win][Direct2D] Add initial D2D GraphicsContext implementation

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Brent Fulgham]

This patch adds a Direct2D GraphicsContext implementation, which will exist in parallel to the existing Cairo and CG implementations.

This patch simply adds the new files. It does not incorporate them into the build.

rs=me, although I feel like this is so much code it should go through real review with someone who knows D2D :|

More extra blank lines!

Why not // comments?

Nit: End with .

Does this need a FIXME?

Same here.

And here.

And probably many other places

Sadly, there seems to be no such person. I'm hoping one of the EA or Sony people will jump in at some point with some advice. Until then, I just want to get this prototype in place so others can build it and hack on it.

It broke the Windows build, see build.webkit.org for details.
