Add possibilty to, while computing nodes:
add more nodes to the task manager,
edit, duplicate and remove nodes without breaking the tasks that are submitted
* add a generic ChartViewLegend component that provides an interactive legend for ChartViews
* rely more on data bindings to control Series visibility and display
* NodeLog: remove intermediate property for Loader
* StatViewer
* keep only one function to load source file
* only send request only after the previous one fully completed
* update deltaTime before initializing charts
* reset "sourceModified" property when source changes
Introduce a new TextFileViewer component with auto-reload feature based on a ListView instead of a TextArea for performance reasons. Uses the text content split on line breaks as ListView's model.
Features:
* auto-scroll to bottom
* display line numbers
* customizable line delegates (e.g.: display a real progress bar)
* color lines according to log level
Usage of DelegateModel for model filtering has not proven to be the most stable solution, and might be responsible for random crashes happening during engine's garbage collection. Implement Loader-based alternative:
* first delegate is a Loader which creates the AttributeItemDelegate if necessary
* compensate spacing using negative height when element is hidden
* use it in MetadataListView and GraphEditor 'add Node' menu
* GraphEditor: forward MenuItem key events to searchBar to be able to continue editing the filter even if it lost active focus
* allow to solo a 3D media from the GraphEditor by double clicking on a node or an attribute with the Control modifier pressed
* consistent with Viewer3D.MediaLibrary behavior (solo on Ctrl+Click on visibility button)
* handle supported file extensions in Viewer3DSettings
* add a ToolButton for duplicating/removing following nodes in corresponding entries instead of having a separate item
* change text when those button are hovered to reflect the change of action
* wording: rename "Delete Node" to "Remove Node"
* ease the deletion of a branch from a given starting point
* accessible with alt+del on a node
* re-order menu to put the most destructive operation (Clear Data) at the very end
* required for PySide2 > 5.11.1 (and compatible with 5.11.1)
* AttributeItemDelegate: test for list length to determine whether to create a slider component (if range is set to None on Python side, it will be an empty list on the QML/JS side)
