Re: opacity, animate and mask

Hello,

if pointer-events is not explicitly noted, the initial
value 'visiblePainted' is used.

I looked in my test case(s) related to this and could
not find any problem with Opera 9.

The relation of opacity and events is maybe comparable
to an opaque glass plate - no matter how opaque it is,
you cannot grab through it, even if you cannot see it.

This is different if you set for example display to none
or visibility not to visible or pointer-events to none, then 
it is possible to 'grab' through to an object below it.
I think in SMIL 3 they want to offer a value for opacity
related attributes or properties, to allow authors to
define, how opaque something has to be to recieve
an event, but this is not the case for SVG (or SMIL 2).

User agents I know to support animation of opacity:
Opera 8 and 9, adobe plugin. 
KSVG1 and Amaya with some specific simple animation types
can animate it too, but they do not care about events.
