Sample improvement: D3DVisualization.cpp - RenderTarget should not be recreated each Render() call #4

From the sample I see that you recreate rendertarget each DoRender() call, which is extremely not efficient in highe performance rendering scenarios. Rendertargets should be recreated only when one of the swapchain parameters changed. Other time DX should reuse existing one.

Would love feedback on the fix.
