SarahW	a7d006b637	Rewrote timer code. ... The new code is based on timestamps, rather than delays. This eliminates the need to update every timer in timer_process(), which cost a non-trivial amount of CPU time on low-end machines. This involved changes to every user of the timer code, so this change almost certainly introduces bugs.	2018-08-02 22:06:10 +01:00
