Native does this in more cases (at least for all bitmap graphics
objects), but using gdi32 objects when we can should perform better.

In particular, releasing a resource that's in use by the device or the
stateblock is always an internal error in either wined3d or the relevant
wined3d client library.

wined3d: Release the previous render target only after replacing it in IWineD3DDeviceImpl_SetRenderTarget().

This is especially silly for FOURCC formats.

The root shellitem was being freed before getting passed to the event sink.
