Changes:
* With this patch we finally removed the LayerIndex class and member
functions to access layers by index (like Sprite::firstLayer/layerLayer
/layer/indexToLayer/layerToIndex() etc.). As layer groups can be
expanded/collapsed, it doesn't make sense to use layer index to
access layers directly from sprite.
* Now we use a layer_t (int) to access a list of browsable layers each
time we want to iterate visible layers in the timeline.
* Replaced CelsRange() and Sprite::uniqueCels() param with
SelectedFrames to iterate non-adjacent cels.
* Updated clipboard operations (copy/paste) in timeline to support
layer groups.
* Updated Timeline control to support selecting multiple layer/frame
ranges with Ctrl+ or Alt+click (fix#1157)
* Added more test units for DocumentRange operations (mainly for
non-adjacent ranges).
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).
Undoers were little objects to swap/revert an action. They didn't
execute the action itself, they just revert its previous state. Now
undoers were replaced with cmds: A cmd is an object that
executes/undoes/redoes just one action.
Changes:
* Remove old undo library and app/objects_container_impl.cpp
(now we use the doc::ObjectId directly to store undo info)
* Remove all Undoers from app/undoers/
* Replace DocumentApi impl with little Cmds in app/cmd/, these
cmds handle execute/undo/redo of each action at the logic layer
* Remove doc::Dirty object
* Remove doc::Settings: all undo configuration is in the app side
* Move undo options from app:ISettings to app::Preferences
* Rename UndoTransaction to Transaction
* Create a CmdSequence to store a sequence of Cmds (as now the new
undo library doesn't support open/close groups)
* Add doc::get<T>(ObjectId) function to get any kind of object
from the doc library by its ID
* Add Cel::document() and Sprite::document() members
* Add Sprite::cels(frame_t) to get all cels in the given frame
* Add Layer::displaceFrames() member function
* Move the "allow non-linear history" flag from undo2::UndoHistory
to app::DocumentUndo
Changes:
* Add doc::ImageRef to count references to the same image between Cels
(at this moment we cannot generate linked cels anyway)
* Remove doc:Stock class and doc::Sprite::m_stock member variable
* Remove app::undoers::Add/RemoveImage
* Add doc::SubObjectsIO and app::undoers::ObjectIO to
replace doc::LayerSubObjectsSerializer
Changes:
* Create render library (move util/render.cpp to render/render.cpp)
* Move app::Zoom class to render::Zoom
* Remove doc::Image::merge() member function
* Add gfx::Clip helper class (to clip dst/src rectangles before a blit)
* Move doc::composite_image() to render::composite_image()
* Remove doc::Sprite::render()
* Replace Sprite::getPixel() with render::get_sprite_pixel()
* Remove doc::layer_render() function
* Convert DitheringMethod to a enum class
* Add AppRender to configure a render::Render with the app configuration
* Move checked background preferences as document-specific configuration
* Add doc::Sprite::layer() and palette() member functions
* Add doc::Layer::cel() member function
* Add doc::Palette::entry() member function()
* Add doc::frame_t type
* Move create_palette_from_rgb/convert_pixel_format to render library
* ExportSpriteSheet doesn't need a temporary image now that we can specify
the source rectangle in the render routine
- Merge Timeline::STATE_MOVING_LAYER/CEL/FRAME to STATE_MOVING_RANGE.
- Remove celmove.h/cpp and move_cel/copy_cel functions. Now they are
in the Timeline as dropRange/Cels/Frames/Layers member functions.
- Add DocumentApi::copyFrame/moveCel/copyCel member functions.
- Add timeline_drop_layer_deco and timeline_drop_frame_deco skin parts.
- Move code from DuplicateLayerCommand::onExecute() to new member
function DocumentApi::duplicateLayer().
- Fix a bug changing Cel's frame number: we weren't updating the Cel
position properly inside the LayerImage::m_cels collection. Now we use
LayerImage::moveCel() to change the Cel frame number.
- Other fixes to DocumentApi: Change bgcolor from int to color_t.
- Add HAVE_CONFIG_H wrapper to #include "config.h"
- Removed widgets namespace (it's in app now)
- Move some functions from src/file/file.h to src/base/cfile.h
- Move Vector2d to base library
- Rename MenuItem2 to AppMenuItem
