+ Activate a repeating timer event.
+
+ This starts a timer which will send a timer event to `view` every
+ `timeout` seconds. This can be used to perform some action in a view at a
+ regular interval with relatively low frequency. Note that the frequency
+ of timer events may be limited by how often update() is called.
+
+ If the given timer already exists, it is replaced.
+
+ @param id The identifier for this timer. This is an application-specific
+ ID that should be a low number, typically the value of a constant or `enum`
+ that starts from 0. There is a platform-specific limit to the number of
+ supported timers, and overhead associated with each, so applications should
+ create only a few timers and perform several tasks in one if necessary.
+
+ @param timeout The period, in seconds, of this timer. This is not
+ guaranteed to have a resolution better than 10ms (the maximum timer
+ resolution on Windows) and may be rounded up if it is too short. On X11
+ and MacOS, a resolution of about 1ms can usually be relied on.
