/* revision history:
* gimp 1.1.17b; 2000/02/23 hof: bugfix: dont flatten the preview, just merge visible layers
* bugfix: for current frame never use diskfile for the preview
* (to avoid inconsitencies, and to speed up a little)
* added "Show Path", pick and drag Controlpoints
* gimp 1.1.17a; 2000/02/20 hof: use gimp_help_set_help_data for tooltips
* added spinbuttons, and more layout cosmetics.
* gimp 1.1.15a; 2000/01/26 hof: removed gimp 1.0.x support
* gimp 1.1.13b; 1999/12/04 hof: some cosmetic gtk fixes
* changed border_width spacing and Buttons in action area
* to same style as used in dialogs of the gimp 1.1.13 main dialogs
* gimp 1.1.8a; 1999/08/31 hof: accept anim framenames without underscore '_'
* gimp 1.1.5a; 1999/05/08 hof: call fileselect in gtk+1.2 style
* version 0.99.00; 1999.03.03 hof: bugfix: update of the preview (did'nt work with gimp1.1.2)
* version 0.98.00; 1998.11.28 hof: Port to GIMP 1.1: replaced buildmenu.h, apply layermask (before rotate)
* mov_imglayer_constrain must check for drawable_id -1
* version 0.97.00; 1998.10.19 hof: Set window title to "Move Path"
* version 0.96.02; 1998.07.30 hof: added clip to frame option and tooltips
* version 0.96.00; 1998.07.09 hof: bugfix (filesel did not reopen after cancel)
* version 0.95.00; 1998.05.12 hof: added rotatation capabilities
* version 0.94.00; 1998.04.25 hof: use only one point as default
* bugfix: initial value for src_paintmode
