- slider DisplayType enums sink to node/sliderdisplaytype.h (canonical
engine home); FloatSlider/RationalSlider alias them for compatibility
- DropWithoutSequenceBehavior enum sinks to common/dropworkflowbehavior.h
- Config errors now go through a registered ErrorHandler hook instead of
QMessageBox with a MainWindow parent; the style default no longer
depends on the UI style manager
- MainWindowLayoutInfo moves to node/project/serializer/ and its panel
dependency is reduced to a plain std::map alias (PanelLayoutInfo),
breaking the engine -> PanelWidget -> KDDockWidgets chain
- ProjectImportErrorDialog moves from task/ to dialog/projectimport/
- remove confirmed-redundant UI includes and give project.h/import.h/
project.cpp the direct includes they were borrowing transitively
- project.h includes folder/sequence headers directly (it used both
types in its own API all along)
There were a lot of issues that arose from trying to make GUI changes
from another thread (even though we ran those functions in the right
thread). Now we store layout information until the end of the load and
make the changes then. This works much better from both a business logic
and user experience perspective.
Also prevents multiple sequences from taking focus during load and
starting a render job.
