Previous to OpenGL 3.1 and in OpenGL 3.1 with GL_ARB_compatibility,
implementations are required to expose at least one configuration with
an accumulation buffer.
Marking them as slow has always been a bit dubious. They are marked
this way because the accumulation operation is done in software, but
everything else runs as normal. The GLX spec says:
"...if it is set to GLX_SLOW_CONFIG then rendering to a drawable
with this configuration may run at reduced performance (for example,
the hardware may not support the color buffer depths described by
the cnfiguration)..."
This isn't exactly the case with visual with accumulation buffer. It's
just some operations that are slow, and that's always possible.
Since these visuals have been marked like this since day-1, I'm not
inclined to change them now.

Can I consider that a 'Reviewed-by:'? :)
