Spec anomaly - opacity

I notice that opacity is specified as a float value, implying an inordinate (and completely untestable) set of gradations of alpha; while colour alpha is specified as only 255 steps. This seems completely skewed to me.

I would recommend that we align opacity and colour alpha by specifying <alpha> expressions as component-value.

Whether we wish also to anticipate 16bit colour is a separate question we probably ought to look at.
