Hoo boy. No, you haven't.  This is one of my biggest gripes about SDL 1.2: that
SDL_Video is so tightly coupled with SDL_Event processing.  I'd love to see the
two separated.  It would be especially bad to have SDL try to handle input if I
embed an SDL surface in a GUI form that I've created in Delphi, because Delphi's
Application object *also* takes over input handling for any windows you create.

Ideally, SDL_Events should be its own subsystem, completely independent of
SDL_Video.  If that's not possible for some reason, there should at least be a
specific exception for windows that SDL didn't create itself: If you set it up in an
existing window, assume that that window already has control of event handling
and don't try to take over.  Perhaps provide an API option to allow it to take over
if the programmer decides that would be appropriate in this case?
