Some extra changes introduced:
* DocUndo & CmdTransaction were simplified: removing the saved
counter, and storing a specific UndoState pointing to the state that
matches the version in the disk
* DocUndo::onDeleteUndoState() can generate a
impossibleToBackToSavedState() if the saved state is deleted. This
might fix some bugs where a "save changes" dialog weren't displayed
after undoing and making changes (probably related to #3542, but not
sure)
Some extra work is needed to avoid showing the "save changes" dialog
if we are close to the saved state and only non-modification undo
states separate us from there. E.g. if we open a file, select the
canvas, and close it, Aseprite now shows the "save changes" dialog,
this wasn't true in previous versions.
In this way we can export each grid cell/tile as an individual sprite,
and use the extrude option on each grid cell. We've added the
--split-grid CLI option too.
Now we can export one (or several) tilesets in one sprite sheet (using
the same options that are available in the Export Sprite Sheet dialog,
e.g. like extruding tiles, related to #1982 in some way).
Some changes:
* New "Source" field and fromTilesets param for ExportSpriteSheet
command
* New ExportTileset command (which acts like ExportSpriteSheet but
with fromTilesets=true by default)
* Added --export-tileset CLI option
Regression in dd0c29620974e56d9e62653804b996740a89e88a (Use
tooltip_text style & color to paint tooltip windows #2554).
Prior this fix, text box does not update its bounds area because it
has not a style assigned.
Fix#3442, fix#3443
This was changed in df33744c85833d4f9042871dd9b417c2f2b8654e, but now
we're adding an option to switch between both behaviors. We prefer to
keep the old behavior as the default one and the new one as an
optional preference.

* Remove "%3d" for integers (just use "%d"), this is a legacy format
when the text was a monospace font (it was present from the very
beginning of the times, when we used the Allegro font)
* New :delta: icon (before :offset: which didn't exist in the theme)
* Show useful info for MovingCelState: mainly cel bounds
