+ Add a warning when exporting RGB sprite to GIF, hinting at the quantize function.
+ MovingPixelsState: Add undo information in each transformation step.
+ Add IntEntry class in src/gui/ with spin-buttons.

Refactoring
-----------

- About Signals/Slots: Add some field in slots to avoid disconnecting
  them from dead signals.
- Eradicate JList.
- Replace JRect & jrect with gfx::Rect.
- Create gfx::Region to replace JRegion & jregion.
- editors_ -> MultiEditors class widget
- convert all widgets to classes:
  + match Jinete design with Vaca library.
  + move all functions (jwidget_*) to methods in Widget class.
  + the same for each widget (e.g. jbutton_* to Button widget)
  + AppHooks to Vaca::Signals
  + Convert all JI_SIGNAL to base::Signals
- all member functions should be named verbNoun instead of verb_noun or noun_verb.
- all functions to handle an object should be converted to member functions:
  - e.g. jwidget_set_text -> Widget::setText

High priority work
------------------

- Ctrl+T should transform the current cel
- fix bilinear: when getpixel have alpha = 0 get a neighbor color.
- fix sliders in Tools Configuration, they are too big
  for small resolutions.
- rewrite palette-editor to edit multiple-palettes.
  - fix quantize (one palette for all frames, one palette per frame)
  - pal-operations (sort, quantize, gamma by color-curves, etc.);
  - complete palette operations, and palette editor (it needs a slider
    or something to move between palette changes)
  - drag & drop colors.
- if there is activated the Tools Configuration dialog box, the
  Shift+G and Shift+S should update it
- add two DrawClick2:
  - DrawClick2FreeHand
  - DrawClick2Shape
- see the new Allegro's load_font
- finish ICO files support.
- add "size" to GUI font (for TTF fonts);
- layer movement between sets in animation-editor;
  + add all the "set" stuff again;
- fix algo_ellipsefill;
- view_tiled() should support animation playback (partial support:
  with left and right keys).

Wish-list
---------

- dacap wish-list:
  + added starred file-items in the file-selector.
  + tweening of cels (translate, scale, rotate)
  + tweening of polygons
  + selection of frames (to modify several frames at the same time)
- manuq wish-list:
  + layer-with-constant-cel
- Mateusz Czaplinski ideas:
  + when move selections, will be good the possibility to see relative
    position from the starting point of movement;
  + make drawing the 'marching-ants-rectangle' a prioritaire thing to
    draw (when move it).

Low priority stuff
------------------

- add unit-tests for "raster" and file formats.
- test routines: load/save_pic_file, load/save_msk_file,
  load/save_col_file.
- fix the fli reader (both Allegro and Gfli): when a frame hasn't
  chunks means that it's looks like the last frame;
- talk with Elias Pschernig, his "do_ellipse_diameter" (algo_ellipse)
  has a bug with ellipses of some dimensions (I made a test, and a
  various sizes have errors).
