layer.pickAt (Auto-Select, the canvas right-click layer list and the Move
tool's rollover highlight) read the raw layer-mask pixel, while the
compositor uses LayerMask::value, which applies density (1 - d*(1 - v)).
A hide-all mask at density 0 shows the layer in full, yet the click went
through to the layer below.
Read the mask through LayerMask::value, as the compositor does (it also
returns 1 for a disabled mask). Regression test covers the click and the
list form.

Photoshop's Background is the bottom layer of a file without transparency: a pixel layer that is
transparency- and position-locked, whatever the file's language calls it ("Hintergrund", "背景",
"Arrière-plan"). We matched the name "Background" in compose (deep / shallow knockout), the
engine (cut/clear, merge visible, transforms, warps, distort, erasers, styles, masks, crops,
straighten, smart-object unpack) and the UI (Properties, layer row, tab title), so a localized
file's deep knockout revealed transparency instead of the Background.
- `Document::background` / `background_mut` / `is_background` and `Layer::has_background_traits`
in the doc model replace every name check; `extra_cmds::background_to_layer` is the one
"Background → Layer 0" conversion.
- PSD import marks the bottom record position-locked when it is transparency-protected and has
no transparency channel, with or without an `lspf` block. Affinity import and HDR Toning now
lock the Background's position like every other place that creates one.

With Auto-Select on (or Cmd held with it off), a Move-tool drag that starts where
no layer has pixels (an empty spot, or the pasteboard) now draws a marquee instead
of moving the previously selected layer. Releasing selects every layer whose
content touches it (Auto-Select: Group selects their outermost groups); Shift adds.
New engine command layer.selectInRect; the UI side lives in move_box.rs.

* Move tool: highlight the layer Auto-Select would pick on rollover (#2834)
With the Move tool and Auto-Select on (or ⌘ held while it is off), hovering
the canvas outlines, in the theme accent, the layer (or group, per the
Auto-Select target) that a click there would pick. Preferences › Tools ›
Show Highlight on Rollover turns it off (on by default).
The hover asks the click's own hit test (pick_cmds::auto_select_target, now
shared with layer.pickAt), so a type layer is outlined anywhere inside its
text and fully locked layers are clicked through, as on a click. The answer
is cached per document revision and pointer pixel. Nothing is drawn while a
button is down, a drag or transform runs, or the selected pixels would move.
Part of #214 (scorecard TOOL-214-4, now partial).

layer.pickAt hit-tested every layer by the alpha of the pixel under the
pointer, so a click in the gap between a type layer's letters picked the
layer under it. Like Photoshop, Auto-Select (and Cmd-click) now hits a
type layer anywhere inside the bounds of its rendered text. The
right-click layer list still lists only layers with pixels there.

- Layer > Duplicate on an artboard stacked the copy exactly on the original, so
nothing visible happened. The copy now goes right of the board (100 px gap,
sliding past boards in the way) with its contents, and the canvas grows to
show it, in one undo step (single and multi-layer duplicate). `inPlace: true`
keeps the old behaviour; the Move tool's Alt-drag and Alt+Cmd+T use it.
- Move tool Auto-Select ignored artboards: a press on an empty spot of a board
picked the Background under it, so the drag never moved the board. A click
there now picks the board (layers on it first, clipped to the board; Group
mode stops inside the board), and the drag moves the board with its contents.
- Moving a board past the right/bottom edge grows the canvas, as a new board
does, instead of cutting it off.
