This handles an edge case where a user deletes all unmagnified nodes,
leaving a final node that is still magnified. Because we ignore
magnify/unmagnify operations when there's only one leaf remaining, this
would result in the last node being stuck magnified until a new node is
added.
Also fixes a bug where the layout would not always update when a new
block was added.
Fixes an infinite loop in the layoutModel atom synchronization that
would cause the atom to update indefinitely when the root node is
deleted.
Also adds a dedicated `disabled` flag for the IconButton decl so we can
disable the onClick handler when the button is disabled.
Also updates the Magnify toggle button to use this new flag, so that
when there's only one leaf in a layout, the magnify button is disabed.
Adds a delay to the resize handle line first showing so it doesn't flicker when the mouse briefly passes over it. Also removes an unnecessary findNode call that was happening on every move. Also adjusts the pointer offset based on the display container bounding rect.
Rather than using a timeout to debounce changes to the
NodeModel.innerRect, I'll use a transition event on the display
container. This way, if the user disables transitions using the reduced
motion setting, changes to the innerRect value will not be debounced.
Adds a flag to the insert layout action to explicitly set the focus of a
newly inserted node. This also adds a flag in the starter layout to
focus on the terminal block.
Make the block content sizing update once when its node moves or becomes
magnified. By manually updating this inner sizing rather than letting
the block flow in the DOM, the animations of the block frames are much
smoother.
This also fixes an issue where two scrollbars were being rendered for
the Directory Preview widget.
This also sets zero padding on nodes when there's only a single node
being rendered.
Fixes the in-memory focused node stack so it can be used to find the currently-focused node. This is necessary for `closeFocusedNode` to work. Also fixes `validateFocusedNode` so it will set the first node to be focused if no focused node is available. Also cleans up leafOrder update pattern.
This adds a new NodeModel, which can be passed from the TileLayout to
contained blocks. It contains all the layout data that the block should
care about, including focus status, whether a drag operation is
underway, whether the node is magnified, etc.
This also adds a focus stack for the layout, which will let the focus
switch to the last-focused node when the currently-focused one is
closed.
This also addresses a regression in the resize handles that caused them
to be offset from the cursor when dragged.

This simplifies the rect calculations by making the gap between pixels
into a padding applied directly to the leaf nodes. This means the gaps
won't be present in the overlay layer, so when dragging a node around it
is always over an OverlayNode and the pendingAction won't be unset.
Also simplifies onDrop handling
This PR is a large refactoring of the layout code to move as much of the
layout state logic as possible into a unified model class, with atoms
and derived atoms to notify the display logic of changes. It also fixes
some latent bugs in the node resize code, significantly speeds up
response times for resizing and dragging, and sets us up to fully
replace the React-DnD library in the future.
