radeon: bug #1462, predownscale to make HD video work.
Use the overlay scaler's predownscale capability to make videos with large
horizontal resolution work if it exceeds the scaler buffer width. Make the
scaler buffer width user-configurable since we don't know it for all chips,
and using predownscaling may otherwise reduce quality even if it wouldn't
be needed. This should fix bug #1462.
