Before actually working on the new proposal I tried to fix two
inconsistencies of the macOS platform. I committed one fix
(87475c20d6cc81912e) and created PR #248. Manolo, could you please
review the PR?
OK with this change.

I'm uncertain about what is expected by Fl::repeat_timeout().
Its general goal is to schedule a new timeout at a given delay (δ) after the previous timeout
(last_t) was scheduled. My question is "what should Fl::repeat_timeout() do when it runs after this
delay expired (after last_t + δ) ?". The current implementation for the macOS platform prioritizes the regularity
of timeouts, and schedules a new timeout for last_t + n * δ where n is the smallest integer value that puts this date in the future.
I believe the Unix platform implementation prioritizes the running of timeout callbacks and
has the callback run several times without delay.

What do FLTK developers believe should be the priority of Fl::repeat_timeout()?
