This change is the first step to create a mini editor with the capability
to show the animation while we edit other frames. Also it will allow us
to have two or more editors of the same document in different frames.
- Added DocumentLocation: now the location in a document is a property
of the current Context (Context::getActiveLocation()).
- Added ContextAccess/Reader/Writer classes.
- Added DocumentApi class: high-level API with the majority of methods
in UndoTransaction class (that were not directly related to a undo
transaction).
- Added AddFrame/RemoveFrame undoers to handle add/remove frame correctly:
this fix issue #212.
- Removed SetCurrentLayer/Frame undoers.
At this moment the button isn't functional because the current frame
position is stored in the sprite (instead of the Editor). In this case,
when the "play" button is pressed, the mini-editor should show other
frames instead of the current one (should play the whole animation).
Now we have one editor for each Document we want to edit. Before we were
creating one editor and switching the document on it, but now we have
several Editors (one for each opened Document). This simplifies the
Document implementation, because it doesn't need to know temporal
Editor information (like "preferred editor settings").
- Removed all code from modules/editors.cpp (legacy from C code).
- Removed PreferredEditorSettings class and
Document::getPreferredEditorSettings().
- Added Workspace/WorkspaceView classes.
- Added DocumentView (a DocumentObserver).
- Added MiniEditorWindow class.
- Removed SelectFileCommand & CloseEditorCommand.
- Added TabView interface instead of using a raw void* in
Tabs/TabsDelegate classes.
- Modified editors_draw_sprite() calls to Document::notifySpritePixelsModified
notifications.
- The "current_editor" global variable wasn't removed because it's
used in several places yet, but it will be removed in the near future.
(Also this variable now can be NULL when we don't have an opened
document.)
