[AD] GUI double clicks and presses

[George Foot <gfoot@xxxxxxxxxx>]

At the moment, the GUI code sends a MSG_*PRESS when you press a
mouse button, but then goes into a double-click checking state,
where it won't pass through any further MSG_*PRESS until it's
sure the event wasn't a double-click.  Even then, it sends a
MSG_DCLICK message but not a MSG_*PRESS, it seems.

IMHO the system should pass through all mouse presses with
MSG_*PRESS messages, even if they're part of a double-click.  To
me the press and release messages feel lower-level than the
click/dclick messages.

On 5 May 1999, when Vincent offered to implement the press and
release events, he and Shawn were discussing this, but I can't
see a conclusion back then.  What do other people feel about
this?  I'd like to rework the doubleclick system so that it
doesn't have this side-effect (I think this could be as simple
as just moving the lower-level press/release tests to occur
before the double click tests).

If anyone wants to look, here are some details of Vincent's
message:
