Hi Ivan,

  That's what I had in mind in the beginning, but others like Eric 
Lemoine convinced me not doing so.  The purpose of the BBOX strategy is 
to toggle the protocol.read when necessary and the purpose of 
OptionsByZoom is only to change the layer's protocol and format options 
before doing anything else.  This is a different behavior than the BBOX 
strategy.  Also, this strategy could be used with other ( not yet 
implemented ) strategies.

  I agree with the fact that it's wrong to have a strategy dependent of 
an other.  Also, it won't work if you declare it after BBOX because it 
won't trigger its options changing events before.

  What do you think ?
