For next release
----------------

+ 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.
+ Add feedback to "Shift+S" shortcut to switch "snap to grid".
+ Convert jaccel::key_list to std::vector<>
+ Shade drawing mode.
+ Add color swatches bar.
+ Sort palette entries.
+ Add "Remap" button to palette editor after a palette entry is modified:
  This button should apply a color curve to the whole sprite to remap
  old indexes to the new positions.
+ Move launcher.cpp to base/ lib adding an extension point for "gui" lib.
+ Move src/dialogs/aniedit,filesel to src/widgets (remove dialogs/ directory).
+ Merge everything related to configuration/settings in one class
  (allow configuration per document). Use cfg.cpp and settings/ dir.
+ Refactor src/file/ in several layers.

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

+ Command::loadParams() should be called one time when the command
  params is read from the XML file, not each time the command is
  executed. For this all commands must be got from the CommandsList,
  then cloned, and finally filled with params.
- 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).
