here's a patch to output "TICK" every time a timer timesout

The problem is basically for battery life on e.g. a laptop. Ideally if office
is open on a laptop and you're not doing anything with it you don't want the
office to be running constantly waking up your processor and eating battery
life if it has no work to do.

This commit
http://cgit.freedesktop.org/libreoffice/core/commit/?id=388486a510c8f5b04132a614fa5f2c330d229248
and this description https://issues.apache.org/ooo/show_bug.cgi?id=106487#c0 is
a good example of what I mean, i.e. changed "always running a timer to layout
equations" to "run the timer to layout equations only when the equation has
changed"
