As the split (after Enter key press) splits the BLOCKQUOTE up to
the BODY, it's necessary to backup all of that. Otherwise, when
splitting in the second or higher BLOCKQUOTE level, the undo does
not have correct information and misbehaves.
The changed places rely on the visibility of the widget including
the parent widgets, not only whether the GtkWidget::visible is set
to true.
An example is when replying to a message when the preview panel is
turned off while it had been showing a different message in it
before being hid. In that case the composer opened with the message
in the hidden preview panel, instead of the message selected
in the message list.
That happens when the .ics file does not contain timezones referenced
by the component properties. Also check for the builtin timezones
as if the TZID was a location.
This allows to save JavaScript plugins, files with .js extension,
into `$PREFIX/share/evolution/webkit/preview-plugins/` or into
`~/.local/share/evolution/preview-plugins/` for the message preview
and into `$PREFIX/share/evolution/webkit/webkit-editor-plugins/` or
into `~/.local/share/evolution/webkit-editor-plugins/` for
the WebKit composer.
The plugin is an object, which contains two members:
* `name` - a string with a name of the plugin
* `setup(doc)` - a setup function
The argument of the `setup` function is a `document`, which can
be either the main document or an iframe document. The function
can be called multiple times for the same document.
The preview plugin registers itself by calling `Evo.RegisterPlugin(plugin_instance)`.
The WebKit editor plugin registers itself by calling `EvoEditor.RegisterPlugin(plugin_instance)`.
This could happen when the Evolution had been started in the Tasks view
and then switched to the Calendar view, the task panel was left empty.
It was because all the task lists had been opened already, thus none
emitted the "client-opened" signal, thus the related data model did
not have added the clients.
This applies to the memos panel as well.
* remove more built files, not needed during runtime
* generate appdata release information from the NEWS files
* add cmark dependency to the development manifest
The Flatpak renames the 'evolution' icon to the 'org.gnome.Evolution',
thus use that one under Flatpak, to have it available in the notification
bubbles on the host system.
The old change causes runtime warnings with WebKitGTK 2.34.0,
thus stop sending fake signal to the WebKitGTK and count with
the case when the cached link hover will not update the status
bar text.
