Add the ability to render a XAML tree to a direct3d texture (offscreen rendering) #144

API suggestion
Early API idea and discussion, it is NOT ready for implementation

Milestone
Currently WPF offers the ability to render a xaml tree to a bitmap via RenderTargetBitmap.
Yet this API forces the client to do a copy of the render target to system memory (and back).
It would be much better if it would be possible to gain access the Direct3D9 render target.
There could be various applications to this feature. 3D game overlays, Heads up displays etc.
Here are several discussions on this issue:
