This is a first iteration of the feature, it doesn’t have handles to
move the symmetry line and it only contains two symmetry modes:
horizontal or vertical.
As an extra change, we have added the new Stroke type to wrap a vector
of gfx::Points and simplify some existing code in the ToolLoop.
Now the default palette is saved in the user configuration
directory, so we can set any palette as the default (it doesn't
matter if it's related or not to a file, it will be copied into
the user directory anyway).
Now the ContextBar contains a set of brushes. The ChangeBrushCommand
supports a new "slot" parameter and "change" = "custom" to select a
specific custom brush from the ContextBar. Alt+1, Alt+2, etc. are mapped
to this ChangeBrushCommand (see changes in gui.xml).
Also, as the ButtonSet that represent different brushes in the ContextBar
uses icons generated from the brush, we don't need the skin parts that
represent each brush type (we can generate those icons from some standard
brushes). Those skin parts were removed.
This is to avoid leaving commands with old params (a problem with
keyboard shortcuts). To make sure, we've changed arguments from Params*
to Params&, so we always have params to load.
Also, in this change we introduce a new way to give parameters to executed
commands from menu items using AppMenuItem::setContextParams(). Before
showing a popup, we can call setContextParams() to give extra params to
the command (e.g. the specific FrameTag to remove or change properties).
In this way "contextparams" attribute for <item> in gui.xml is not
available anymore.
Add a new contextparams attribute to menu items in gui.xml that are feed
by the UI with params (e.g. the FrameTag popup needs to know what exact
tag we should edit, and it's a command Param provided by the Timeline).
Renamed Preview to FullscreenPreview to avoid confusion.
As an extra "to do", we need to add command aliases, so Preview matches
FullscreenPreview (mainly to keep user defined keyboard shortcuts).
