Non-rectangular shapes in Windows RT and Windows Phone
Please allow us to use non-rectangular polygon shapes with Windows.UI.Xaml.UIElement.Clip in Windows Store apps development. This would help us port the fancy controls (like wpfbookcontrol.codeplex.com) in Windows Store and WP8 worlds.
WOW! wpfbookcontrol is looking FANTASTIC! Too bad we can't use it in WinRT at this time...
