ddraw: Adjust the d3d viewport when changing the back buffer.

WineD3D sets up the viewport according to the front buffer, so this needs to be changed to the values of the render target passed when the d3d7 device is created and this device turns out not to be the known front or back buffer.

ddraw: Adjust the d3d viewport when changing the back buffer.
