I have an idea for an additional MIDI option: a function like this:


void trail_midi (MIDI *trailer, MIDI *main_midi)

Plays the midi structure trailer, then loops main_midi until a stop_midi
is sent or sound_exit or allegro_exit or exit is called.
If stop_midi is called during the trailer, the trailer is stopped and the
main_midi does not get run. (It is pre-empted).

Purpose: This will enable making a piece of music that loops to a point
after the beginning, by making it in two MIDI files. Example from another
p[latform: Super Mario Bros plays a very familiar theme tune for the first
level of the original game. There is a sequence of seven notes at the
start of the music that introduces it but doesn't recur when the rest of
it loops. Being able to do this type of thing in Allegro would be nice.

(It can be done in a way right now, by running the trailer and then
polling for midi_pos becoming -1. But that is clumsy and prone to errors
or speed limitations.)
