Changed the name of the new function from "add_interval_timeout" to

"repeat_timeout", which is shorter and more accurately describes what
it does.

GLUT_STROKE_*_ROMAN in glut.h are defined as 0,1 on WIN32 to match the
glut header files there.

@ -303,23 +303,25 @@ Add a one-shot timeout callback. The function will be called by
<tt>Fl::wait()</tt> at <i>t</i> seconds after this function is called.
The optional <tt>void*</tt> argument is passed to the callback.
<h3><A name=add_interval_timeout>static void Fl::add_interval_timeout(float t, void (*cb)(void*),void*v=0)</A></h3>
<h3><A name=repeat_timeout>static void Fl::repeat_timeout(float t, void (*cb)(void*),void*v=0)</A></h3>
Add a one-shot timeout callback. The difference from <a
href=#add_timeout>add_timeout</a> is that the time is measured from
when the last timeout callback was called, rather than from the moment
this function is called (if no timeout has been called recently the
time is measured from the next call to Fl::wait). This is designed
for making regularly-spaced timeouts at high speed (like for movie
playback), it also has slightly less system-call overhead than
add_timeout.
Inside a timeout callback you can call this to add another timeout.
Rather than the time being measured from "now", it is measured from
when the system call elapsed that caused this timeout to be called. This
will result in far more accurate spacing of the timeout callbacks, it
also has slightly less system call overhead. (It will also use all
your machine time if your timeout code and fltk's overhead take more
than <i>t</i> seconds, as the real timeout will be reduced to zero).
<p>It is undefined what this does if called from outside a timeout
callback.
<P>This code will print &quot;TICK&quot; each second on stdout, with a
fair degree of accuracy:
<UL><PRE>void callback(void*) {
printf(&quot;TICK\n&quot;);
Fl::add_interval_timeout(1.0,callback);
Fl::repeat_timeout(1.0,callback);
}
