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 new renderer uses a shader to paint only the checkered
background. It can be tested only in ENABLE_DEVMODE and pressing F1
key to switch between the renderers (which is a devmode special key
for testing purposes only)
We've changed the Renderer::renderSprite(Image*, ...) member function
to renderSprite(os::Surface*, ...) so we receive the os::Surface
directly to paint the SkCanvas with a SkShader. Probably more
refactors will be needed.
If we start playing from a tag with a repeat field, we'll just play
the tag as many times it says and continue with the regular animation
of the sprite. Users expect the repeat field to be useful with the
default configuration of the program.
Now the equivalent was "{tag}_{frame1}.png", but it looks like a
regression reported here https://community.aseprite.org/t/17253 were
it was possible to just specify the frame number as in "{tag}_1.png"
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.
This "undoing" state (introduced in b43f2a3428)
is used in the scripting AppEvents (a ContextObserver) onActiveSiteChange()
impl to trigger a 'sitechange' event for scripts/plugins so they know
if the change was from a undo or from the regular user interaction
(some scripts will add more actions to the transaction if the change
is from the user, not from a undo/redo, or now with this fix,
navigating the history)
This was a source of crashes for the Attachment System when using the
Undo History (e.g. https://github.com/aseprite/Attachment-System/issues/83
+ using the Undo History window)
