Much better.

I will point out though that there be all sorts of worms here when you
come to the previous ARM evaluation boards (which is why the capabilities
stuff got written in the first place) where there's a horrid mixture of
BGR/RGB ordering at various levels of the system - some of which must be
set correctly because the CLCD output isn't strictly used as R bits
G bits and B bits (to support different formats from the CLCD's native
formats.)
