This avoids to open a document two times on Mac OS X
from the command line (the file is loaded when we
process the command line, and by Finder, which send us
an application:openFile: message).
The objective of these changes is to create a more testable doc/logic API.
Included changes:
- Added doc::Context, doc::Documents (the old app::Documents),
and doc::Sprites (and observers for each)
- Added raster::Sprite::createBasicSprite()
- Added doc::ColorMode (equal to raster::PixelFormat)
- Added some methods to doc::Document: context(), sprites(), sprite()
(to replace app::Document::getSprite()), width/height(), colorMode(),
name(), and close()
- Moved app::DocumentObserver/Event to doc::DocumentObserver/Event
- Replaced app::ContextObserver with doc::DocumentsObserver and a couple
of signals.
- Renamed app::Context::getActiveDocument() with
doc::Context::activeDocument()
- Renamed app::Context::getActiveLocation() with
app::Context::activeLocation()
- Removed app::ContextObserverList
- Removed app::DocumentId (now we can use doc::ObjectId)
- Removed app::Context::getSettings()
