/* revision history
* 1.1.9a; 1999/09/21 hof: bugfix RUN_NONINTERACTIVE mode did not work
* 1.1.8a; 1999/08/31 hof: accept anim framenames without underscore '_'
* 1.1.5a; 1999/05/08 hof: bugix (dont mix GDrawableType with GImageType)
* 0.96.00; 1998/07/01 hof: - added scale, resize and crop
* (affects full range == all anim frames)
* - now using gap_arr_dialog.h
* 0.94.01; 1998/04/28 hof: added flatten_mode to plugin: gap_range_to_multilayer
* 0.92.00 1998.01.10 hof: bugfix in p_frames_to_multilayer
* layers need alpha (to be raise/lower able)
* 0.90.00 first development release
