Windows 7 includes a new, hardware-accelerated API for 2D graphics, Direct2D. We should investigate using this in WebKit to see if we can benefit from its increased performance and better feature set relative to GDI.

We should also compare it to CoreGraphics, of course. Since Direct2D will only be available on Windows 7 and later (and on Windows Vista with an optional update), we'd need to be able to fall back to different rendering path at runtime. Also, CoreAnimation has dependencies on CoreGraphics, so we'd probably need to keep CoreGraphics around even on Windows 7 and later.

Was it for AppleWin port or win-cairo? @Fuji & @Brent - for any input on whether it is still applicable?
@Ahmad: This was for both Windows targets, and is still relevant.
Although Windows 7 is not! :-)
