Call C<$function> for horizontal lines which intersect C<$region>.
C<$spans_ref> is an arrayref of x,y,width horizontal lines. If
C<$sorted> is true then they're assumed to be sorted by increasing y
coordinate (allowing a single pass across the region rectangles).
C<$function> is called
&$function ($x, $y, $width, $data)
for each portion of a span which intersects C<$region>. C<$function>
must not change C<$region>.
$region->spans_intersect_foreach ([ 0,0,50, 20,20,100, 0,10,50 ],
0, # spans not sorted by y
\&my_callback,
'hello'); # userdata
sub my_callback {
my ($x, $y, $width, $userdata) = @_;
print "$userdata: $x, $y, $width\n";
