2/2 winex11: add XRender based GetSrcAreaStretch

[Roderick Colenbrander]

Good to hear. There are various optimizations which I still have to
make which can boost performance some more. For instance in case of
SRCCOPY (means a direct copy from a source to a destination without
any fancy blending or some bit-wise operation) I can save a 'memcpy'
and I don't always have to recreate XRender Pictures which could also
help. Performance will get better :)
