I started out by testing the Frameranger demo in Wine. A fixme printed
was that conversion from D3DFMT_A16B16G16R16F to D3DFMT_A8R8G8B8 was
unimplemented, so I implemented that. Then I tested it successfully
both on Wine and Windows.

However, as Wine is in code freeze right now I decided to only send a
patch with tests for the existing format conversions.

Right now I am a little confused, as the Microsoft reference does not
mention conversion from D3DFMT_A16B16G16R16F to D3DFMT_A8R8G8B8.


Also, to fix the Frameranger demo: Would it be better to make it avoid
software blitting entirely?
