[Kst] Events and historical data

[George Staikos]

   I've been getting requests to "fix" events in Kst when used with historical 
data.  The problem is that we don't really support this at all.  How should 
we deal with it?  How often should an event trigger, when should it trigger, 
and which types of actions should happen when scrolling data?  What would the 
cut-off point be? (ie: right-edge, left-edge, centre, scroll-direction-edge, 
user-defined, other?)  What do we do with Y-scrolling?  For that matter, how 
do we deal with plots that have multiple Y for a given X?  It almost seems to 
me that this concept begs for a "cursor".

   Points of interest:  People seem to be using the scripting hooks but I 
haven't seen anyone using the other types of event actions.  Maybe we should 
focus on this as the common case.  It seems more useful to me anyway.
