what happened to function load_dir_to_array ?

In 6.1 there was this function (load_dir_to_array) in the brilliant_gallery.module file

In 6.3 it seems to have disappeared from the file, even though it is still called (lines 388, 637):

$temp              = load_dir_to_array($absolpath, $imagewidth, $fullresolutionmaxwidth, $brilliant_gallery_sort);

Anyone know where that function (or whatever replaced it) went??
