Try to support Direct2D 1.1

[Jingwood]

Considering upgrade the API from Direct2D 1.0 to Direct2D 1.1 in order to support more excellent features and effects.

Pros.

• More excellent features and effects available
• Rendering support for Windows Store apps *1

Cons.

• Can't support the old Windows platforms (Windows 7 without update package and older)
• Performance degradation?

Resources

• Introducing Direct2D 1.1
• Migrating to Direct2D 1.1

All suggestions are welcome.

Can't support the old Windows platforms (Windows 7 without update package and older)

Is it even worth to bother with as it is not supported any more?

Waiting for Direct2D 1.1 supported

Cons:

• Performance degradation?

Is there any evidence to suggest there'd be a performance hit here? My primary use case for this library is speed of rendering.

Also, why not jump directly to 1.2 or 1.3? I'll admit I'm not so familiar with what each version brings.

Folks who need to target earlier versions could stay on the 1.4 package.
