// Because the client and server have a shared memory space for event data,
// but use different indexes for the event (servers cache them all upfront, 
// while client creates them as sequences fire) we're going to store the server
// index in the low word and the client index in the high word.
//
// studio.h is a public header, so we'll use this matching struct to do the
// conversion and not force us to macro all the code that checks the event member.
// This struct's data MUST match mstudioevent_t
//
// BUT events that use the old event system use the entire dword which will always
// match between client and server. Instead of wrapping everything in if checks, 
// for ( type & AE_TYPE_NEWEVENTSYSTEM ) we use the Event accessors to set/get 
// while doing the check under the hood.
