Vincent Beron <vberon@mecano.gme.usherb.ca>
- Fix various function prototypes.
Jeremy White <jwhite@codeweavers.com>
- Revise winmm/time.c to fix timer resolution at 1 ms. This then allows
a much more efficient implementation of timer events and timeGetTime,
and callers that used sub 10 ms resolution will now get correct
results.
Hans Leidekker <hans@it.vu.nl>
- Fix signed/unsigned comparison warnings.
Eric Pouech <pouech-eric@wanadoo.fr>
- bring the multimedia doc up-to-date
- moved the TODO from the doc into the code

* FIXME
* We're using "1" as the mininum resolution to the timer,
* as Windows 95 does, according to the docs. Maybe it should
* depend on the computers resources!
* Some observations on the behavior of winmm on Windows.
* First, the call to timeBeginPeriod(xx) can never be used
* to raise the timer resolution, only lower it.
*
* Second, a brief survey of a variety of Win 2k and Win X
* machines showed that a 'standard' (aka default) timer
* resolution was 1 ms (Win9x is documented as being 1). However, one
* machine had a standard timer resolution of 10 ms.
*
* Further, if we set our default resolution to 1,
* the implementation of timeGetTime becomes GetTickCount(),
* and we can optimize the code to reduce overhead.
*
* Additionally, a survey of Event behaviors shows that
* if we request a Periodic event every 50 ms, then Windows
* makes sure to trigger that event 20 times in the next
* second. If delays prevent that from happening on exact
* schedule, Windows will trigger the events as close
* to the original schedule as is possible, and will eventually
* bring the event triggers back onto a schedule that is
* consistent with what would have happened if there were
* no delays.
