Not being at all familiar with this code, I'm not sure where to get the
framebuffer size. The function sets:

UINT fbwidth = src_surface->currentDesc.Width;
    UINT fbheight = src_surface->currentDesc.Height;

I updated the patch to use those variables, even though they have the same
values I was using before.
