This already fixes a lot of possible problems that can happen when a
script is running and modifying some part of a sprite that is being
backed up in a background thread.
We still need some work to being able to lock a sprite two or more
times in the same thread to write it. E.g. an app.transaction() should
lock the sprite for write access, but the script transaction function
could call a command, and that command could use a ContextWriter to
lock the sprite again. At the moment this is not possible because we
need a re-entrant RWLock implementation.
Added a new Events object with :on() and :off() methods to start or
stop listening to a specific event respectively. This also allows to
add several callbacks for the same event.
Replaced the temporal Site.onChange & Sprite.onChange implementations.
Related to several issues (enable more possibilities for): #138, #1403, #1949, #2965, #2980
* As we moved the VERSION macro to a .c file, we don't have to
recompile the whole project when we change the version number.
* Removed the version number from gui.xml
* Removed the invalid first menu item that might appear in the root
menu when the gui.xml version is outdated in debug mode.
This is the first commit with a simple tilemap editor. Still buggy but
functional in several ways. Several changes were made:
* NewLayer command can receive a tilemap=true to create a new tilemap
layer
* New ToggleTilesMode command added to switch between the palette and
the tileset in the ColorBar (the ColorBar was expanded to show
colors or tilesets with a generic AbstractPaletteViewAdapter)
* All commands to create new layers were moved to Layer >
New... submenu
* There are a new tileset chunk to save tilesets in .aseprite files,
and a new kind of cels to save tilemaps
* Added doc::LayerTilemap, doc::Tileset, etc. and several other types
to handle tilesets/tilemaps in the doc layer.
* Added doc::Grid class with grid specifications that indicates how a
tilemap <-> tileset must be drawn
* Added and expanded cel operations to work with tilemaps and
conversions between regular LayerImage cels <-> LayerTilemap cels
(e.g. copy cels in the timeline between layer types)
This function was called app.drawWithTool() first, but some tools do
not "draw" (e.g. eraser, selection-like tools, etc.). And then the
app.toolStroke() name could be confused with the Edit > Stroke
command.
