What do you want to do? Do you want to replace white by transparency? This
is easy (not only in perl-fu, btw), just use plug_in_colortoalpha, e.g.:
$layer->colortoalpha(WHITE);
If you just want to replace a specific colour index (e.g. in an indexed
image) you can also use select_by_color and selection_clear.

This usually suffices: "$layer->add_alpha".
