Description Adam Roben (:aroben) 2009-05-29 12:44:57 PDT

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

See <http://msdn.microsoft.com/en-us/library/dd368038(VS.85).aspx> for more information about DirectWrite.

Since DirectWrite 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.
