Windows.UI.Xaml will it be completed to support for missing features?

Question

Features in WPF not implemented fully in Windows.UI.Xaml.

UIElement is missing Geometry clipping limited to RectangleGeometry

UIElement is missing OpacityMask

DrawingContext and VisualBrush are also missing.

All these features are native to DirectDraw/DirectX 11.1 so why are they missing?  Just does not make sense to me.

Answer 1

WPF is almost 10 years old.

WinRT is young.

Answer 2

You can post and vote on feature requests at the Windows Platform Dev feedback site at http://wpdev.uservoice.com . Your request will have more impact of you explain why you need the feature and the scenarios it will enable for you.
