Is there a legitimate reason that users would need to configure this, or is it just to work around the fact that the new version is incomplete? -- Alexandre Julliard julliard(a)winehq.org

Whether it's a legitimate use-case is up for debate, but there are known currently working applications that will try to use the new functionality tied to ID2D1Factory1 once that's exposed. I'd say it's a fairly large chunk of functionality, so it may take a while before it's all implemented.

Shouldn't the option default to disabled then? -- Alexandre Julliard julliard(a)winehq.org

Possibly. In a similar situation in e.g. wined3d I'd default to not exposing the new interface, but I expect, perhaps naively, that currently working Direct2D applications are a fair bit less prevalent. I'd happily change this to be disabled by default though.

If we include this before 3.0, then yes I think it should be disabled. But it may make more sense to defer it, and add it enabled by default after 3.0 is out. -- Alexandre Julliard julliard(a)winehq.org
