   StretchRect in d3d10
  Is there an equivalent method in d3d10 for IDirect3DDevice9::StretchRect?I know there is ID3D10Device::CopyResource, but it won't do a stretch.   
  There isn't. You'll have to draw a quad.   ;  If you don't need to do it in realtime, D3DX10LoadTextureFromTexture is a possibility (I don't know how fast it is). The DX FAQ says also that this replaced StretchRect in a way..
