Before this fix, when the thumbnail size was 1, the "Toggle Timeline
Thumbnails" command (F6 key) seemed to not work until we changed
the timeline thumbnail size to 2 or more.
The default language (en.ini) has a new "display_name" property, but
probably we should remove it and transform the English language in an
extension (just as the default Aseprite theme).
Before this fix, when installing dithering matrices if Aseprite
couldn't find the file of some matrix described in the json, Aseprite
would crash (this happened during the installation of an erroneous
dithering matrices extension, and after every reboot of Aseprite).
The cause of the crash was the absence of the MainWindow instance
during the ContextBar creation. When an error occurs, the console is
called, but since MainWindows is not yet available, aseprite crashes.
This is needed on X11/Linux as we received a lot of mouse events at
the same time when the user drag the mouse. In this way we avoid
restarting the preview and making a high CPU usage just to stop/start
the filter without any kind of UI feedback.
Added FILTER_LOOP_THROUGH_ROW_BEGIN/END macros to simplify some
boilerplate code for each filter.
In this way if processing just one row takes too much time, canceling
the operation is faster.
We can use a thread pool (avoid creating/destroying threads) and we
can continue the same task running when the filter restart (there is
no need to stop/wait and restart, because the filter task keeps
calling the applyStep() function anyway).
Several changes were included:
- Fixes in TextBox widget to show it with proper size hint when it's
outside a viewport
- Added the IncompatFileWindow with a message + link to know how to
update Aseprite and solve the situation
- Moved CannotModifyWhenReadOnlyException from app/doc.h to
app/transaction.h
This is the first attempt to finally implement the require() function
on Lua. The main problem was how to solve conflicts between plugins
that use the same library name. Here we separate each plugin like in a
namespace, so require(name) inside a plugin will save the module in
_LOADED["pluginName/libraryName"] to avoid conflicts with other
libraryName from other plugins.
* Now a Cel has a z-index property to change the order of layers per frame
* A new doc::RenderPlan class can calculate the order of cels to be rendered
* z-index is saved as a int16_t in the .aseprite files
* This new field can be set/get from Lua with Cel.zIndex
The SimpleRenderer outputs unpremultiplied RGB values when we render
in a transparent background, we have to indicate that to Skia now that
we're compositing os::Surfaces (SkiaSurfaces) directly in this
FullscreenPreview command.
Renderer::renderCheckeredBackground() function was used only for the
FullscreenPreviewCommand, but now we use
ShaderRenderer::renderCheckeredBackground() to render the background
in the Editor too. So the sprite is painted in a backbuffer and then
composited with the already painted background using
Graphics::drawSurface().
This menu was accessible right-clicking the Play button in the
Timeline (and in the Preview window, with specific options for the
Preview).
This change includes some changes:
1. Now if a menu <item> in gui.xml doesn't specify a text field, the
text of the command is used (to avoid double translation, the bad
side is that we don't have a mnemonic specified).
2. Menu::showPopup() can be used with submenus from the root menu, to
do this we have to remove the menu item owner temporarily before we
show the menu as popup (see the change in Menu::showPopup())
3. We can specify a special active DocView for commands with
UIContext::SetTargetView, this is used to set the Preview editor as
active view for commands like TogglePlayOnce, etc.
As the "multiple windows" feature is still buggy (#3556) and we've
disabled it by default, it's nice to make this option more visible (in
the General section) so users reliant on this will find the switch
quickly.
We cannot delete a tileset yet from Aseprite UI, but now an extension
can do it through Sprite:deleteTileset(). Deleting the non-last
tileset will create an Tilesets array with an empty (nullptr) slot on
it (so tileset indexes are not changed, and for the future, if some
external file is referencing that tileset index, the reference will be
kept).

This is to simplify code and to match ui::MenuItem::Click and
ui::Button::Click signals (so then we can write some generic code
using Button::Click or MenuItem::Click).
If the current UndoState doesn't modify the "saved state" (e.g. there
is a sequence of undoes/redoes that doesn't modify the saved version
of the sprite compared to the current one), we can indicate that we
are in the saved state anyway (!Doc::isModified).
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.
So now we can have access to Skia SkPaint instance directly from
Aseprite UI code (and set the shader, and other properties that are
not yet well-wrapped in laf-os).
We've simplified ui::CheckeredDrawMode with
ui::set_checkered_paint_mode() function, as now the checkered
background shader is stored in ui::Paint (SkPaint) instead of
ui::Graphics state.
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
m_undoHistory is not valid for tabs other than sprites. For example
opening the README or Home tab does not initialize the undo history,
thus aseprite will segfault when it tries to get its first entry.
