--- Comment #5 from Eric Anholt <eric at anholt.net> ---
Daniel: the problem is that normal apps use the alpha, but they don't fill it
with values that should be used to blend window contents over other windows. 
So you must not return the rgba visual when people aren't really looking for
the rgba visual.  Nothing in the change was about performance.

We should certainly be exposing EGLConfigs that match up to the rgba visual,
though, so you can find it when you try.
