Windows uses Point sampling when stretching from a DirectX BackBuffer to the WIndow
===

Windows7 is using point filtering to stretch from my DirectX9 back-buffer to the window client area.  When the window is resized the artifacts from the stretching look very bad.  We can avoid this by changing the back buffer size, but that requires calling IDirect3DDevice9::Reset().  This results in a black screen and a small delay while resizing is happening.

Is there any way to improve the filtering method windows uses?  Or, Is there any way to update the window from a different DirectX surface such as a Render Target?
